What is the limit of trash talk in boxing/MMA

[champion4ever]

I believe that family members and ethnic groups should be left out of trash talking altogether; It's because after all, I'm the one who is going to be dishing out the asswhoopings not my family or people. They are innocent.

However at the same time a professional prizefighter should anticipate that his opponent would do or say just about anything in order to gain a psychological edge over them.

So, as long as you can back it up you can say whatever you want?

Well if you all that and then lose it's all the more embarrassing like Broner against Maidana,if your gonna talk, you better back it up
