It is a tricky issue. It may be disproportionate, and most people of whatever variations are just trying to get with their lives.
- But perhaps it gets so much attention because some trans people - mostly biologically male - and others - get very strident and insist trans women ARE women. Saying that offends many ordinary folks' sense of logic and reason and biology.
- One can 'feel' like a woman, perhaps, but that is also tricky, and touches on an even older debate about discrimination than gay rights etc - because women have been struggling against men telling them how they think for over a century, you know? It feels like an erosion of women's hard-fought rights when a man can state "I feel like a woman inside". *(see note 1).
[and these two points may suggest WHY MTF gets more attention]. because it is biological males who lead the charge and are more confrontational in general; because of our biological sex *(see note2), and hormones?]. Perhaps its also relevant that FTM gets less attention because biological females are less disposed to 'making a fuss', due also to biology.
Re 3. The issue is not much bathrooms, as for example natural-born men entering women's sports and women-only spaces. Eg it becomes a problem when male bodies - being faster and stronger - compete against female bodies (that's obviously why women's sports were set up in the first place). There was that unedifying spectacle of a trans MTF beating up a woman in boxing a few years ago. And more pertinently, women-only spaces such as (most) domestic abuse support groups set up for females who've experienced domestic abuse and violence from males. Some women naturally feel uncomfortable being around ALL men, which is why they are female-only groups.

(i find that a ludicrous thing to say. At the end of the day, we all feel like ourselves, and we are different. And if some people want to have a group called LGB, then that is their choice, surely. And including the T in lesbian gay etc, surely suggests that it is same-sex attraction, also. Which as I understand it, some on the trans side strenuously deny, when saying trans women ARE women).

Whether one agrees or not, the UK Supreme Court ruled last week that there only two accepted genders, in law.
