On the back of @Barearse's post the other day I did my own small survey of the men in my life (1 DP, ds1(29), ds2 (17)) and asked what their reaction would be if a TIM went into the men's loos.
"I don't care, so long as they don't act weird in there"
"So long as they follow 'the rules', same as any other bloke"
"Yeah it's fine. No-one really cares"
So based on that, it seems that there doesn't even need to be a campaign for men to 'Be Kind'. Most men are the same- TIM or not, so long as they don't look at another man's penis or stand at the urinal next to them if there's a spare one next-door-but-one, they just Don't Care.
TIMs have nothing to fear. (apart from some olfactory assault probably. They could use their energy to campaign for better conditions in the men's loos)
