I'm going to use the word roles. Ultimately the whole transpeople thing annoys me as they are still trying to fit into social gender roles rather than say 'i don't accept them at all'.
I agree, on the whole. We just have to be careful to understand the complexity of gender and social gender roles, and how we define those. What is a role? A behaviour. I'm sure you and I both want the role of police officer to be available to both sexes, so that kind of behaviour we can think of as a social gender role that was at one time reserved for males and denied females. We want gender role equality.
But we (I hope you agree) don't want all behaviours to be equally acceptable or available to either sex. I don't want males (I'll use my terms: men) 'chestfeeding' or menstruating or getting pregnant, nor do I want them simulating those things in their delusion. I don't even want medical science to waste resources on trying to make those possible. We might designate those behaviours, then as 'sex roles'.
To answer 2. I think there are females that want to take on social opposite gender roles (man) and males that do the same (woman), their sex doesn't and cannot change with present technology.
Yes. But that doesn't answer my question. Are those males who take on women's gender roles 'men', and vice versa? That is what your statements about labels of toilets seemed to suggest. You would label one of them "Females only" admitting people (whom you describe as men according to gender roles) because they are female.
If that doesn't describe your view, what is it, and why doesn't it make more sense to stick to the ancient definitions of men and women, as terms expressing sex? This still allows men to wear dresses and women to go to war, equality of social gender roles.
Gender has become a big thing, whereas I wish it didn't exist at all and people just be themselves without pressure to conform to that nonsense. It does exist unfortunately so I just have to deal with it.
I agree. In fact, I'd say gender doesn't exist, there are just behaviours that we associate with one sex or the other, some of which either sex can, and should be able to, exhibit (i.e., we should loosen those associations) and some of which are, and should remain, the remit of one or other sex.
This is further complicated by the existence of behaviours that either sex can physically accomplish (walking through a door into a particular room; using a shower; joining a particular sports team, scientific study or social group) that the law ought to separate by sex, because of the different needs and wishes of the two sexes.
