Now this is NOT the reasoning you (and many others) have stated for why "nice normal gays and lesbians" hate pedos. On the contrary, they hate the pedos "because they make the rest of us look bad" and "because they make it harder for us to gain acceptance in the mainstream" and "because they make it more difficult for us to achieve our political goals."

For at least some of the fags and dykes, fag rights is just the avenue of attack they think has the maximum chance of success under the civil rights regime: "Most trooned children would grow up gay, this is gay genocide!!!1!" Similarly, there are people who shout about the absolute supremacy of parental rights, but most them would say parents have no right to troon or otherwise rape the kid. People understand troons are evil, but they can't say it because muh civil rights, so they have to resort to intellectually dishonest proxies and pick out a tier on the oppression totem pole.
Professional racists don't believe it's possible to outright cancel civil rights (that'd be
anti-black), so they're trying to expand them to whites. There are lots of dishonest anti-child-mutilation campaigns trying to work the civil rights angle: Muslims, Armenians, autists, gays, rapist troons who reject the current state of stinkditch art and demand cancer-level funding for designer fuckholes.
Now, I don't know whether the fag angle good and effective. I'm Russian, I hope we can dig in here and kick out all the letters except Z and V (Russia is close to passing a proper anti-troon bill -- not the "true trans" pamphlet that was floated last winter but a real "no sex changes, ever" thing). I can talk shit on the Farms, I can talk shit IRL. But you guys get raided by pedophile cops out there. It's possible that the fags and dykes strive to be effective (even if they're doing it wrong).
The other reason I'm inclined to believe in LGBs is the trend they "selfishly" claim to be worried about is the second derivative. Troons have won massive privileges for gay grifters and pedophiles. Even if "acceptance" is trending down, the momentum is still plowing on, but when the troons lose, the rainbow grift will have been rolled back, too. A truly selfish gay or dyke will not live to see the total collapse of the GAE, so it's more advantageous to throw xir lot with trannies.
