I'm not going to let them do it either my anonymous friend, but joining silly groups isn't going to stop them either.
People need to get out on the streets, campaign against them in public, attend their election meetings and ask awkward questions.
Most important, vote against them, make your vote count by voting for the candidate most likely to beat them, forget political allegiances in the name of beating them. If that's how strongly you feel, that's what you need to do.
Not exchange idealistic posts in an obscure web forum. Which is not a political forum anyway.
