The proper response to transphobes is 1) "you shouldn't say x", and if they don't, 2) "shut up, idiot". There's some subset who would be respectful but don't know that certain things are disrespectful, that's what #1 is for. The rest are just idiots trying to fit in with their fascist group dynamic. They'll happily out themselves when you ask them to speak respectfully, so for them, it's #2.
If they try to have an argument, just respond to everything with "who cares? leave them alone."
There's lots of polemic comments on the other post as well, but I did like this thing someone there said, about how the greatest impact can be made in real life, where the bigot in question, has a real person in front of him, making it much harder to dehumanise them.
Online, there probably isn't much to be done to change someone's mind.
When in person, if he is still an asshole, treat him like the asshole that he is.
There is no point in debate when you can't agree on basic facts. A lot of transphobes are living in their own bubble, having completely rejected relevant experts in psychology, medicine, and many other fields.
I'm actually a transphobe. It's not natural for cars to turn into giant robots, you know how hazardous it is to be around transformers? With their size I wouldn't trust them to see normal folks like us and they might accidentally step on us leading to injuries and at worst death. Transformers are abomination and an insult to god. Banned transformers!
They won't change their desire to be hateful people, they'll just ignore your logic that contradicts their world view. The only people that can change their opinion will be their friends, not the people they're convicted are their enemy.
Start working on the ones willing to listen.. it'll be a slow process to undo decades of political indoctrination but it's possible. It requires finesse and a gentle approach of friendship and kindness.
Then shove a stick up the ass of the political leaders driving this idiocy and cook them alive above a fire on a spitroast with an apple in their mouth.
Anyone who is on the fence about is the earth is flat is definitely not worth your time to convince its round because their critical thinking skills are retarded.
The same logic goes for people who are on the fence thinking universal human rights for all minorities is something bad.
Stop wasting your time. You kill their toxic culture from its roots by agressively protesting, voting and deterring religion from interfering with politics, as well as promoting ownership and training of firearms for minority groups that are vulnerable to sexist/racist/genderist law enforcement in order to deter them from forcing you into a corner with threats of violence, or it will grow back like a rotting putrid festering fungal slime.
Not gonna lie fam, I was looking for a way to link the source post, that was less creatively dead than "Source post: √link". But I think what I said is a hella good point in a post with enough upvotes, that I was going back to it via "Top of last week", because it is that highly upvoted.
