May I politely suggest there is a tad of imagination going on here........I rather doubt you would be able to find any Democrats, Labour supporters, Navara media or Joe politics that have suggested any of your examples.
Maybe you have got yourself a bit triggered by culture wars??
lets look at 1) "you can change your sex" -nobody is saying that, what they are saying is you can change your gender. It is true Democrats support trans rights, but trans is a minority group so why shouldnt they be supported? If you had a child that grew up Trans I am sure you would want their rights represented
lets look at 5) "there are 32 genders" whilst people are born biologically male or female, not every person feels they match the gender of the biological they were born with, but they dont necessarily feel they are 100% the opposite gender, the might be anywhere between male and female, so rather like autism, gender is a spectrum, a range.
I personally cant stand all these silly pronouns, I dont think it helps the trans community at all, but the fact is, there are more than 2 genders
