I find that a bit of an odd question. I think people do currently feel societal pressure to be accepting of LGBTQ people. I don't think that's necessarily good or bad by itself - it just reflects the changes in society.
Should parents feel pressure to be accepting of their children's lifestyle if they come out as LGBTQ? Yes.
Should parents feel pressure to be accepting of their children's desire to transition if they identify as a different gender? No, because that's permanent, there's a good chance they'll later come to view that as a mistake. If they still want to do that as an adult - then that's when they can do it.
To try and get back to what I think you're digging at - should girls be pressured into sex acts in porn which used to be seen, or are still seen, negatively because they're more normalized now thanks to porn? - No. I don't think people should be pressured into sex acts.
Would you say the same thing about homosexuality or transgenderism ?
