Peace no Muslim can honestly say that Dr Zakir Naik advocates terrorism, the reason for intentionally backing the media is because of your other problems with him. Look at the previous video to see his contrasted stance against terrorism and the real reason why UK want him out. It is because he openly declares the purpose of the media engine.
I don’t agree with his stance on Yazid, but at the same time I don’t agree with your stance on Sayyiduna Abu Bakr (RA), Umar (RA), or Uthman (RA), it doesn’t mean I should have you boycotted for a statement of yours that I take out of context.
