Should I boycott my father who watches satellite TV, even though I have admonished him with wisdom and good counsel?

Question:
He says: Honorable Shaykh, may Allah grant you success, my father, may Allah guide him and grant him success in all good, watches satellite TV, and sometimes my sisters are with him. I always admonish him with wisdom and good counsel, but to no avail. I always boycott him, but then I regret it and return to him, and I kiss his head. What is the solution in a case like this? May Allah grant you success.

Answer:
The solution in a case like this is that you advise your sisters not to sit in front of the satellite TV, and not to sit with this father who has not accepted the advice. You should advise your brothers and sisters not to sit with him. As for kissing his head and greeting him, this is not appropriate; leave it until he repents and desists. However, being dutiful to him by giving him what he needs and serving him is permissible, because that is part of being dutiful to a parent. As for being friendly with him and being casual with him, leave that until he repents to Allah the Exalted. If you, the family, had been strict with him, had boycotted him and kept your distance from him, perhaps he would have removed this satellite TV and been saved from it. But since you are not firm with him, he continues.
