It's not about fighting individual gay people or trans people. It's that the idea of gay and trans is being weaponized to take away our freedoms. Look at all of these hate speech laws, they're restricting our ability to speak and communicate. I don't think it's good for the right or the left, science or the church, west or east, to be able to tell other people what they can or cannot say or can or cannot do. Our laws should be the bare minimum of keeping peace, the government is not trustworthy enough to be safeguarding morality. It doesn't seem like they have any anyway.
So to reiterate, a totalitarian tyrannical government is using the agenda of trans and gay to take freedom away from individuals. This is why they fight.
