Some people haven't learned the aspect of disagreeing and will in lack of better jump to personal attacks / stigmatizing name-calling with all the worst things their mind can comprehend, or simply try to attack the grammar, and punctuation for a non-native English-speaking-user.in lack of valid arguments.
Hopefully, such people will grow out of it, otherwise, they tend to end up very lonely.
