If you are a BSL user that is...... not if you are a deaf person that doesn't sign. I suppose that means when they DO learn how to lobby they will just be lobbying about BSL and nothing else, which does no-one else any favours. These people have no other cause to talk about and rarely understand the issues of others or care.
Here is the Idiots guide to lobbying MP's or any politican, and it's FREE !
(1) Work out the issue you want to raise, cut the waffle, list facts in proper order, look up online for people already raising similar issues so you aren't repeating what has already been done, do NOT use emotional or 'we have rights as deaf people' avenues, identify where the issue is, and why it discriminates against you in your area, don't waffle about what other areas do, what charities tell you what to do etc, or your MP will refer you to that area, and/or another MP, end of your complaint.
(2) You can look up your MP HERE
(3) Write to them, or post an e-mail, all the links are on your MP's site. If you can't write find someone that can.
(4) If you want face to face, ASK them for that, and check when they are at their 'surgeries' and available to talk to. They are obliged to provide you with interpretation so ask at the same time, DON'T turn up without asking for that and expect it will be there anyway, to make some silly point of non-access, you won't get sympathy that way. Start as you mean to go on, not scoring points for your pals. Martyrdom only works with your mates, it has no effect on others.
(5) Ok, you discover your MP doesn't give a shit, (Most don't, they have your vote who cares what you think until election time ?), or responds with reams of bumpf or links to obscure files guaranteed to frustrate you into submission, maybe they will patronise you and suggest you ask a social worker or a charity, tell them to sod off. Most responses are designed to isolate you, divide and rule generally is a pretty successful avenue. All designed to put you off, try another tack, find out his/her political and local opposition and use them to put the points, play them off against each other, all's fair in love and access. Know your subject, unless you are being specific to yourself, don't start with 'deaf people..' they aren't interested in your views on others, only in YOU, or, write a book/blog or something, and join the que..
(6) Don't rabbit on about campaigns that are not about YOU, or waffled about on social medias, your MP won't be interested, (I don't give a hoot either).
(7) Read your local medias, websites/newspapers etc, get your head out of the closed deaf community and engage with the communities around you, get aware of local issues, show you have more about you than deaf moans, since this engenders zilch support in the wider community if you are talking about yourself and showing no interest in others. What makes you special ? If you can link your issue to local areas, all the better.
(8) As this is about London no doubt there are more minority groups than fleas on a dog or cats backside, but they enjoy nothing more than helping you, as this gives them Kudos, even if they don't give a shit about deaf access, they have to justify their funding, if all else fails threaten to complain that as minority rights group they are discriminating too, be a pain the arse. Don't get too pally, familiarity only breeds contempt. You don't want to end up at their meeting yapping about Yiddish rights or gay Whaling or something.... Personally I was in two minds about minority groups they are a bigger bloody pain than my MP, but they get paid to speak up for you, so make them work for for their money.. Of course it again being London finding one that speaks your language is a downer... they have rights to ignore you as well which doesn't help.
(9) Don't bang on about culture, London as more of them than the bloody UN, and you need to be specific about yours, why does it deserve more response from your MP than anyone else's ? Careful not to say them damn migrants are pinching all your jobs (even if they are it has nil to do with deaf access to your MP), and it being London nobody British lives there anyway.
(10) to get to your MP read their blogs/sites many contain comment areas, USE THEM. If they start creative editing (We've all been there, except 9 times out of 10 they never respond on own sites they have a lackey to do that), then tell your local medias what they are doing or complain to their party leaders, although most of them are deafer than we are, it's worth a try.
Finally AVOID youtube stuff like the above, they are only after your money. Why pay the middle man when you can DIY ? Don't be an echo, you make the first sound.
