"What people get up to in the privacy of their own homes or in the bushes on Hampstead Heath (so long as they are out of sight) is their affair."
But this is precisely the problem. You are tolerant, as long as people keep quiet about it. That's not at all the right sort of attitude. Firstly, because homosexuality isn't just about what goes on in the bedroom and with whom. It's also about being able to be open about who you are. Not necessarily too open, perhaps, we don't need the details -- but it's about being able for a man to talk of "his boyfriend" without fear of judgment, to be open about his relationship in the usual way. And that certainly is something that isn't always possible around the world for gay people. In some parts of Africa it's a criminal offence. That should not be tolerated and we should say so. And those who do not, who continually vote against or abstain from such condemnation, ought to have their motives and values questioned and scrutinised.
In the meantime, as I've commented elsewhere, a good proportion of the rise in UKIP support seems to be coming from the collapse in the vote of other fringe protest parties such as the BNP in particular but also such oddities as NO2EU and the Christian People's Alliance, both of whom saw their vote share and raw vote decrease markedly from 2009. I think a large part of UKIP's surge can be attributed to their establishing themselves as the party to vote for if you want to cast a protest vote. Roughly 8.65 million people voted for the three main parties in 2009, and roughly 8.8 million voted for the three main parties this year, so in total their share of the vote has been barely hit at all and UKIP is merely picking up the scraps.
