What's he supposed to do? He went out of his way to put it in the polite way for you. Unless you want to go into complete incomprehensibility, it's a "rock and a hard place" situation.
Many of mine were also flagged, despite me being extremely polite.
You really have no choice but to phrase yourself in a way that's only recognizable to the in-crowd. Even here, with the polite expression, he is catching flak.
Personally, I don't discuss politics in real life anymore. Risks are too great. Just the Internet, where on some forums (not this one), you can be honest about what you think.
