A machlokes over whether maintaining a given belief makes one an apikorsus? Personally, I wouldn’t want to have a belief that many shittos would deem the person an apikorus — even if according to another shitta he wouldn’t be deemed an apikorus.
As far as the rest is concerned, I’d cite Rav Chaim Brisker: “Fun a kasha shtarbt mir nisht… S’iz besser tzu bleiben by ah kasha vi tzu zugen a krumer teretz.”
