It's not just some idiot talking crap about something you're working on. This isn't a college project. It's someone putting your entire past, present, and future on television and the radio making false claims about you. It's someone making your personal information known publicly so you can receive threats. If you don't have the same dollars as the other guy, it's someone controlling the public narrative to paint you as Satan himself.
It's so much more in depth than taking valid criticism. YOU don't have to pay attention to them, as the person fronting the bill. But the 300,000,000 other people in the US will.
And then, right or wrong, good or bad, you lose. Again, not an insult, but yours is an unbelievably naive view of how politics works.
