You define conservative ideas as fascism in one swoop and now "they" are all evil, all discussion stops, and you fall in exactly the trap you accuse the other "side" of. We do not need sides. There is no "The Right" as much as there is no "The Left".
Of course we need to not allow fascism (and the populist MAGA nonsense), I have stated nothing to contrary.
For the record I tend to be strongly liberal progressive (see my various comments, although I keep politics on HN to a minimum). But I also realize that only liberal progressive ideas are not enough, just handouts do not work, people want jobs through which they can support themselves, we need a working economy, reduce debt, etc, etc.
So, again, I wish we would come together instead of drifting more and more into extremes. If we did come together, we would not have a problem with fascism in the first place. We would not be so easily divide by populists smoke bombs like trans-athletes or alleged violent immigrants.
This is not "hopelessly naive" but intensely practical and necessary.
