Nope, you're not being trolled. Just remember how different each municipality might be. Here, the sewage treatment plant can handle it, as was mentioned by others. Our storm drains, however, drain straight into Wascana Lake, and things like antifreeze would be problematic there.
On the other hand, if I was on a farm with a septic tank, I'm not sure I'd be in a rush to flush antifreeze down the toilet.
