Yes, you can. It’s simple to state your own beliefs during debate without insulting another religion in the process. By insulting, I don’t mean disagreeing with a teaching or a topic, I mean directing insults at a particular religion.
To be clear, though, the following is against the rules as found under Rule #3 of the Forum Rules:
2) Defamation, slander, or misrepresentation of a member's beliefs/arguments, or that of a particular group, culture, or religion. This includes altering the words of another member to change their meaning when using the quote feature.
3) Antagonism, bullying, or harassment - including but not limited to personal attacks, slander, and misrepresentation - of a member across multiple content areas of the forums. Repeatedly targeting or harassing members of particular groups will also be considered bullying.
