Pretty simple answer. No.
The powers that be, namely religious nuts and their peons will run this agenda that being gay is some kind of disease. That's not the case. Like when they said the earth was flat, just because they are legion, doesn't make them right about it. Not all religion is a bad thing, but some twist it with selective memory, bs and quotes.
If a person is gay, trans or whatever and wants to personally change themselves via operations, drugs etc, for their own reasons, that's cool and that's their choice, and no one should tell them otherwise.
There have always been gay, lesbian, bi people on this planet so long as man has walked it, some of them famous. Trans I can't say as that's a fairly recent thing (correct me if I'm wrong). We all should learn to accept people for who they are, not what we want them to be, based on ancient religious books, warped scaremongering minds etc. What's also sad is the many people out there, who are forced by society expectations to live a lie, because that 2.4 children family is the norm.
I was raised Christian but later rebelled to freer thinking. As a result, I've had the privilege to meet some cool gay and lesbian people who I class as friends still. Sure, the unknown can be scary, but they are just people, just like you.
