Actually, I generally prefer discussions about politics and religion...the two topics one is supposed to avoid.

Some of the discussions bore me since there is no really correct answer to the issue at hand, while others are quite stimulating.
Now, as a general rule, I think men and women are different in this respect. I think men, again, as a rule, like and thrive on the debate, while women, as a rule, avoid that type of conflict. Now, I've use the phrase "as a rule" on purpose. There are exceptions to the rule, and I am sure there are ladies that can hold their own, and, indeed, enjoy such a debate.
