If you're not happy about those things, stop telling everyone who disagree with you how stupid they are and how they're literal Nazis. Then at least some of those who disagree with you on some issues will be less driven to vote for the people whose positions appall you.
Depending on where you are from, this could absolutely be true, as "elitist" and insulting as it might be. Well, fascist is more appropriate than Nazi because Nazi is superset of fascism with a heavy anti-semitic element, and I'm not aware of many rabidly anti-semitic parties in the mainstream in many countries.
Scratch a little deeper on the things popular Republican politicians and members of the current administration have been saying and promoting for the last few years.
Conspiratorial movements almost always end up at "it's The Jews", and so do theirs.
If you see talk about their opponents engaging in dark "rituals" involving child murder or abuse, you can be 100% sure you've found one that'll get you there. It's just blood libel, keeping reading and listening and you'll see that they're fully at that point before you've had to do much work. It's tedious.
So for now, I'm billing them as fascist.
Their methods and their positions make them fascist, not their support or lack thereof for opposing positions.
Say, a coup attempt. Or someone in power talking about ignoring term limits. Or getting bribes and favouritism for corporations (corporatism is a heavy component of fascism). Or silencing opposition with brutal and illegal methods (such as kidnapping in the middle of the night by unmarked and masked men). Those all scream fascism, regardless of the fact that e.g. the person in charge of healthcare is an antivaxxer.
Many say it works because liberals now represent the professional-managerial class, who often come across to workers/poor as infuriatingly patronizing, slick and humiliating. Whereas many don't know who owns their big corporation, so they don't inspire such visceral feelings.
While some may argue that liberals aren't leftists (but are rather good-cop), nevertheless many leftists do this too. The dynamics are explained in Thomas Frank's book "Listen, Liberal", David Graeber's essay "Army of Altruists: On the alienated right to do good", and Participatory Economics's coverage of the coordinator class.
Thanks for the pointer, that was a very interesting read.
