NEVER discuss politics or religious issues in public.
It's just not wise to divide your audience in half. Between friends and in private is fine, but in public, as tempting as it may be, it's just not a good idea.
you don't want people seeing you as "the liberal" or "the right-winger", or whatever political buzzword.
You wanna be seen as an ARTIST. The ANIMATOR. The CREATOR, of your unique worlds you make.
