If you aren't informed, get informed. Ignorance isn't an excuse for poorly formed ideas. You have the time to do a bit of research, albeit on what little there actually is available, so take the time and effort to do it. The world can wait to see your post.
People seem to forget, you're entitled to your opinion just as much as somebody else is entitled to point out your opinion is wrong/stupid/uninformed. And if they bothered to bring facts to the table, then all the worse for you. If you can't back up your opinion, anticipate being ridiculed for it.
