Listen. Look at his post:

....Don't use abusive language - "I just think QDCloser & segmunk is one same person. Both of u trolls are saying that my son has a fever. Whoever told u that morons? U can go back to all my comments and my thread i will give a kiss on ur feet u geniuses if u will find a word "FEVER" there. Pls dont pretend that u r sensible when the truth of the matter is that u r STUPID TO THE BONE."....

The paragraph starts with a sentence that admonishes the readers against using abusive language. The next line entails the the most abusive and accusatory content the person can come up with. The same poison line is followed till the very end, with the same intensity.

The reason I told him that he does not know English is that he is not aware of even the basics of the language. Here unfortunately English is the only medium allowed on the forum and if someone does not know it well, it obviously can cause confusion.

The term 'your son' does not mean your real son. It is just a reference made extremely commonly in everyday language. Brit took it in literal meaning. Even someone with the most basic understanding of a language can get this easy concept. He, however, failed to do so. What else would I then tell him except that since there is a huge communication barrier that stands between the two of us, it is appropriate that we do not respond to each other.

Does that mean I do not respect him? What exactly is disrespectful in this?

It is ok for him to call people losers and imposters but it is not ok for me if I excuse myself from talking to him? What double standards are these?
