Do you find religion or politics more uncomfortable to talk about?

It's not that difficult, but you do have to respect that others may have strong views contrary to you own. 

"Yes"

I like both.

Religion I know little about and we almost never discuss it. I only feel comfortable talking about politics with my family, and that is rare.

I enjoy discussing religion and not so much politics. But religion is often more personal. I'm willing to discuss religion with someone else who is equally willing, but not with someone who will take any academic discussion of religion as a personal insult to their beliefs.
