The thing that makes it clear to me that the far left are the 'bad guys,' is their assumption of superpowers.
Specifically, telepathy.
A hard leftist/SJW says: "Sex is a social construct! We should give children hormone blockers if trans has become a fad in their social circle when they're 12 years old!"
A conservative says: "You are incorrect. Sex is readily biologically discernible, and while there are an extremely small number of people with abnormal chromosomes, we aren't going to let that be used as an excuse to sterilize, maim, and permanently damage the health of children who are demonstrably not part of that group. Once someone is an adult, they can do to themselves what they want, though we hope they will do what is healthy and moral."
Hard leftist/SJW says: "What you really mean is that hate LGBT!+ people! You want them to die! You're a ***-phobe and a bigot!"
See how that works? The conservative takes what the leftist actually said, and disagrees with that. They contest the validity of the leftist's claim. Some conservatives are frankly terrible at trying to argue about it, but they argue the actual stated position the leftist has claimed themselves.
The hard leftist/SJW puts words into the conservative's mouth, imputes not just an immoral motive, but also the desire to harm the other to them, and then attacks them for such.
Basically, they claim to be able to read the mind of the conservative, and know that said conservative is actually a hater/wants X protected minority group to suffer. When asked for proof, they'll either cite not supporting a given lifestyle, or fringe groups like Westboro Baptist as representative of everyone more culturally/politically right than Bernie Sanders, or similar. Then they demand the government enforce their ideology on the conservative(s).
This is one of many ways I know that the hard left/SJWs are the bad guys.
