No, patriots just have to love their country. Your country can be a dictatorship, and still be loved by at least some of its citizens.
It's not a good idea to mix up words so that they mean 'good things' or 'what I happen to believe' in. Better to have different words for different things.
The Trump supporters who stormed the Capitol may believe terrible things ... I won't get into that. But the overwhelming majority, like the overwhelming majority of Trump supporters, love their country. (And by the way, 'loving one's country' is not an unqualified always-good thing. It tends to make you uncritical of your government in its dealings with other governments, when maybe you ought to be critical.)
Are there genuine patriots among people who vote Democratic? Of course there are? The problem such people have is that among them, and in influential positions, are people who despise America ... as racist, fascist, imperialist. They focus on the bad things in America and make them the essence of the country. They hate the police, they don't want the military to recruit in the schools, they hate free speech if it's exercised by conservatives or honest liberals, and they hate the tradtional family.
They're people like the New York City Councillors who voted to honor Ethel Rosenberg, the executed Soviet spy. Unfortunately, they are very influential, especially in our educational system, and are increasingly influential within the Democratic Party. (The Democrats let leaders of the Communist Party be their precinct chairmen!)
The main political task of patriots is to break the pro-American base of the Democratic Party away. That's why FH Buckley's book, linked to in a previous post, is so important.
