If You would try to educate them, it could be looking like this. Sorry for possibly abusive language, I hope I wont violate too many rules...
You: "Transpeople are people too. They are born this way and did not choose to be trans"
Bigot: "You are fag, just admit it"
You "Gender and sexual orientation are two different things"
Bigot "Why do You need excuses just to be a fag? Admit that You are one"
You "You are not getting the point, are You?"
Bigot "No, You are not getting it. You are just a sick person whose brains need to be fixed. Too bad Your old man did not beat You up enough when You was a little faggy kid to show You that You can be man enough"
You "I am not a man, I am a female"
Bigot "You were born a man. Take it as a man and die a man. Or should I rather refer to You as "it"?"
Bigot 2 "All fags should be burned on stake, cause thats what the Bible says. Fags were not created by God, they are abominations and should be killed"
You "Bible does not say that"
Bigot 3 "Yes, is does. Go read it for Yourself"
You "Can You tell me where does it say so?"
Bigot 3 "No, I am not talking with fags"
You "Can You argue in civil manner without insulting other people?'"
Bigot 3 "No, its You who cant. Besides I dont see other people here, only a bunch of subhumans"
This pattern can go on and on... Seen it countless times on YT...
Now, go try educate them...
