One of the problems that trans people face is that they're put in danger when they use the bathroom that corresponds to their biological sex. They can be attacked or harassed. And, with all due respect, it is not really your job to tell people where to go to the bathroom, especially when they could be endangered. This is not something the trans community is making an issue; it's conservatives pushing back on something that has been done without any problems for years.
I respectfully request that you do adequate research before commenting on issues like these.
This is a good idea, but too often other people are not willing to use the way you request and it's not safe to do so. Or, on your licenses and other legal documents, your old name can't be changed, and requesting a different name to someone will result in danger of being hurt or even murdered.
Typically, trans people are not trying to hit on someone at higher rates than the general population. And as mentioned it can be life-endangering to reveal your sex. It is not "just common courtesy"; since when has someone told you about their genitals before hitting on you?
Again, I request that you use a less dismissive tone. These are real issues that can result in threats to lives.
Overall this sounds like a pretty backwards country you live in. My advice if one finds himself born in such one would be to move, some societies need longer to be changed than a lifetime.
Other than that nothing you said here sounds like it isn't handled by the law in western countries.
And noone needed to tell me about their genitals so far (their wetness might have been mentioned), since those always looked like what was expected.
