Here's a few arguments off the top of my head that someone might dox you for:
-Whether or not feminism is the cause of the recent emasculation of men
-Whether or not Israel is committing crimes against humanity in Gaza and against the Palestinians
-Whether or not transexual persons should be medically referred to as their original gender or new gender.
-Whether or not affirmative action should exist.
Pretty much any debate that is emotionally charged has the potential for people to try to screw with your real life over it, circumcision is not one of them.
