A major political part in the US at the time I write this has had in their national platform the removal of rights from such people including, but not limited to, the removal of their ability to marry who they want to so it is a bit more than "perceived discrimination".
Yes but gay marriage has been legal for a while, and so now we see the invention of new things to be offended about, like they/them pronouns, and pretending that we don't actually know the definition of a man or a woman or that all that makes a man or a woman is which one they'd like to "present" as that day.
I do recall one of the arguments against gay marriage being that once gay marriage was allowed, they'd move to something else. "They literally just want to get married" was the common retort to that argument, but lo and behold, it is becoming clearer day by day that the "give them an inch" slippery slope argument may have applied here. (I support gay marriage, FWIW.)
Regardless, everyone has been discriminated against at some point in their lives, but evidently, certain groups handle it differently than others.
Said political party is fighting to get that reversed and has begun to make noise that states should be able to ban birth control because they think that Griswold v. Connecticut was wrongly decided [1]
