Regarding transgenderism, progressives will cite research showing a minuscule portion of the brain in role-playing men ("MTF") is closer to female brains than normal male brains and use this to validate their ideas of "gender identity". But sex has always been based on testes i.e. reproductive function, not bell curve averages for BSTc volume or something like that. (And that's aside from the fact that normal "cis" males have had their BSTc volume at the "female" end of the range).
I believe the above arguments are used in discussions where the issue being debated is whether or not sexuality and gender is solely based on a psychological construct. Probably an extension of the age old notion that sexual preference is a 'choice' (absent of biological phenomena).
I never reached a crossroads where I had to contemplate whether or not I wanted to have sex with men, nor do I think most people (other than bisexuals), so why would I think that homosexuals, or people who "feel" like they are a woman trapped in a man's body, ever reached a point in their life where they had to conscientiously make this type of choice? Something biologically determined this for them, just as it did for you and me. Nobody hits puberty and weighs the pros and cons of tongue-kissing other men. It's either repulsive to you or it's not, instinctually.
It doesn't matter whether or not they were born with a penis, if they are questioning their gender in any way at all, it must be a pretty significant feeling. Sexuality is not like choosing between a Honda or a Toyota. I never questioned my own, did you?
Being an outlier on same data plot doesn't give you the right to force me to refer to someone born with a penis as "she".
Who is forcing you to refer to someone with a penis as a "she"? In what context?
Other than the transgender bathroom thing (off the top of my head), I can't see where any of this impacts you, unless you were planning to deny somebody rights using their gender as the basis - which is all I see coming from these laws.
These laws, at least the Canadian ones, simply appear to be saying, if a woman walks into your place of business, but clearly has an adam's apple, you cannot simply say, I don't want to rent/sell to you because you identify as a female. The same as you can't deny someone because they are a Christian, Muslim, 89 years old, black, asian, white, or disabled. It seems that you are coming from the position that you want to insist on said man-in-the-dress call himself Bob instead of Mary, which leads me to question 'why do you care'?
I suppose I could understand if you wanted to argue that all discrimination laws are stupid, and a business should have the right to refuse anyone, and I can understand that, but that's a different argument.
Granting someone equal rights (protections from discrimination) doesn't detract from your own.
