Even if voicing your political opinions is okay, I suggest you not do it. Why, you say? Because even if you lock the entry, people still know who you'd vote for. Obviously, some are more politcal than others, so they'd be offended (Yes, I know there's always someone who's offended). Not only that, it gives someone a reason to not like you, be hostile, or terminate a friendship, in the most extreme case.

Basically what I'm saying is keep it quiet and everybody's happy.

And I think I'll lock this so no arguments arise...
