What's wrong with people in your community taking about the ways you are bad? If there isn't consensus about your goodness, that means you are either bring bad in ways you don't understand or you're being good in ways your community doesn't understand. Either way keeping a conversation going is a big party of the solution. Shutting down the conversion seems like a surefire way to make your relationship with your community worse.
The government funds people who think the current government is evil all the time. They don't fund them because they think the current government is evil, but I can assure you that there are people receiving unemployment benefits, social security, and other "entitlement program" checks that disagree loudly and publicly with the government all the time. (Some of them are probably critical of the same entitlement programs they rely on.)
They get money to eat and pay rent, not to build ideological organizations with the aim to undermine the government. You are talking about somebody completely different.
