Bull feces. The Texas Republican Party has made hating transgender people part of their 2016 party platform, so yeah, it IS about us.
Ahem, from the 2016 Texas Republican Party Platform:
Gender Identity — We urge the enactment of legislation addressing individuals’ use of bathrooms, showers and locker rooms that correspond with their biologically determined sex.This anti-trans plank was in the section of the Republican Party platform entitled Educating Our Children:
Facility Utilization-We support public school facilities such as restrooms, locker rooms and showers being reserved for the use of students based on biological birth gender.
It may also result in loss of your Senate seat. Ask Debbie Riddle and Gilbert Pena how well attempting to oppress Texas trans people worked for them in their respective 2016 House reelection bids.
