Don't really know if his parent support his actions or not.
If they don't support his actions, then really really pity them - who'll want this type of child ?
What they should do is just cut-off all his $$$ & see if he still can Talk C___ Sing Song so much or not.
Freedom of speech, but not until the way he do it.
Basically too free and nothing better to do (because all his $$$ is provided by parent - I suppose).
