What's a foot long and slippery? A slipper.

I used to work at a toy factory making plastic Draculas. There were only two of us, so I had to make every second Count.
It depends. Of course it's fine to have no opinion about, say, which sports team should win the big game, because that doesn't matter. And even on bigger issues like fiscal policy, it's okay to just admit you don't know enough about a complicated subject to have an informed opinion. While I do think it's important to educate yourself as much as you can, no one can reasonably learn everything about everything in order to have all of the right opinions all of the time.
But some issues are both important and clear cut. Like, if someone says they have "no opinion" on whether LGBTQ people deserve equal rights... no, no I will not accept "no opinion" as an answer here. You don't need to read mountains of theory to disavow bigotry, and if anyone tries to give an excuse for why they won't, I'll consider that complicit.
