Ok, I was going to start my own thread about my views, but it does seem appropriate to put them here. I'm not sure if this sounds like a conspiracy theory, I've name changed and I'm happy to be told I'm way off mark and as I've never put it anywhere but in my head before it might come out all wrong but here goes.
The argument about genitals only seems to come up when discussing dating, but I think it's much wider than that and should be included in all the discussions about toilets, refuges, prisons, changing rooms and all sex segregated spaces as for me, genitals is a massive part of why I don't want trans women in my space. Now the answer you usually get from most TRA's is 'what's between my legs has nothing to do with you', and for the most part, I'd agree with them. I truly couldn't care less.
Until they're in my space.
The uncomfortable truth for most penis owners is that a penis can be used as a weapon. The extreme of this is rape, but there is also a whole load of offences, before then, including exposure, wanking in public, voyerism, all of which would involve a penis somehow. If a man decided to use his penis against a woman, most would be able to over power her, shock her, scare her into submission, and no matter the outcome, even if she fights back, it's likely to leave emotional scars. Women do not have the same arsenal.
As women, we have to trust that every male we meet doesn't want to use their penis as a weapon against us. It doesn't matter how big, small, skinny or strong they are, it's the man's choice whether or not to offend against us, if they want to we have absolutley no choice about it and it's horrible.
Now we know the majority of penis owners (including TW) absolutely would not do anything like that, but the problem is, some would and this is the reason we have sex segregated spaces which include toilets, changing facilities, dating sites etc. because we just can't tell who will and who won't.
It's nearly always possible to tell a penis owner, even though there may be a few ambiguous folk, usually within one or two interactions it becomes obvious. We have to treat all penis owners, no matter how they are dressed, with caution. All women will do it instinctively, and I think, that many women are overriding their instinct in order to be kind.
