Like a real president should, Biden does a lot of things I agree with and some I don’t. I thought Obama was one of the greatest presidents in my lifetime but even he did things I didn’t completely agree with. Would I’d rather have someone like Bernie or AOC in the Oval Office? Absolutely (well except he’s to old and she’s to young). Could we do better than Biden? Also absolutely. What I’d love to see is national ranked choice voting and more like 5-6 candidates. I think this would be better for everyone. But Trump is an existential crisis waiting to happen. I’m not sure this country can withstand another Trump presidency. Frankly I’m not sure my health can either. I literally noticed a significant drop in my BP when Trump left.
So yeah, you can be critical of Biden and not a Trump supporter. Frankly if you’re not a little critical of any president regardless of party, you’re not in a party, you’re in a cult.
