Is watching Christian channels and channels of people of innovation, and visiting forbidden websites that benefit America, considered aiding the enemies of Islam and deserving of sin?

It is not permissible to access channels and websites that broadcast false beliefs, corrupt morals, and forbidden things, whether they belong to disbelievers and atheists or to people of innovation and misguidance. It is also not permissible to witness or listen to falsehood, except for one who is well-versed in Islamic knowledge and has a legitimate purpose, such as refuting the people of falsehood, in accordance with the Almighty's saying: "And those who do not bear witness to falsehood, and if they pass by ill speech, they pass by with dignity."
