those "people" are called useful idiots, and they're an essential component in the process of subversion.  they're not neccesarily being convinced to support democrats, they're being convinced to feel ashamed supporting anyone else. they take advantage of the innate fear of being ostracized- othered. the majority of democrats are women because the fear of being othered is much stronger in them. all that is really required is for them to convince people that society is a certain way and that there will be social repercussions that never actually manifest.
