Seriously don't take time to argue with the stupid cis assholes that are like "I'm offended" when you tell them they say bullshit about trans people lives. Or when they are "I may be cis but I know very well the matter about [trans things] and I think that you are wrong".

These people are mainly assholes that won't understand even after hours of explanation. They don't want to understand, they want to be right and to prove you wrong.

So yeah they are assholes and it's better to leave them alone.
