Trust an ignorant demicrap to raise their own faux argument. If you want a hint, ask yourself why you choose among a 1040 (which I suspect you don't use), a 1040A, or a 1040EZ. You probably even pay someone to file the latter for you only to reclaim the interest free loan you stupidly extended the government. I'm fairly certain you don't file an 1120 or an 1120S.
