> If the powers that be are corrupt we can simply keep calling it Lake Ontario
This is the same logic that the right wing used when they disagreed with Obama on some issues, so they blocked his Supreme Court nominations just because anything Obama does must be bad.
Sounds like your social circle is in denial. There are certainly plenty of things Trump, buffoon and graft-a-holic he is, has done that are corrupt. Renaming bodies of water doesn't look like one of them. (Obviously, because he would have renamed it after a donor, or at least after himself.)
I mean, sure, we can all call anything whatever. I can call New Mexico "Best Mexico" or call Washington, DC "Bad Washington" and that's my right. But pretending that there aren't official names for things because we don't like the current guy seems immature. It's clearly within the authority of the government. Talk like this makes me think that people want to just live in a reality defined exclusively by party politics where we just pretend every law or policy made by The Bad Party doesn't exist, rather than try to win elections so we can shape the one actual reality.
