I don't really understand the question here.
You're welcome to vote for Democratic candidates and register as a Democrat. Go ahead and do that please. But, I wouldn't vote for you or want you to be an elected official, precinct committee person, delegate to a caucus or convention. A lot of your ideas will never be public policy because they're ridiculous, regardless of party or ideology.
They're not that ridiculous in retrospect when you consider that other developed nations have adopted some of them.
The question was whether or not I would be the subject of scrutiny from my fellow Democrats because of some of my more conservative views.
Specifically, we're not going to start a war with Mexico over drug trafficking. We're not going to put people to death for selling drugs. We're not going to apply your impractical approach to immigration and drug trafficking.
You also ignore several important facets of the policies you critique like drug trafficking through non-Mexico land border ports of entry and skilled labor immigration.
That's unwelcome as bad policy generally, not based on ideology.
