The left arent regarded as radical. A small subset of the left is regarded as radical. Those who want to ban flights, ban meat, reward and penalise people based off what some of their ancestors did 200 years ago, reject the scientific value of vaccines, advocate for population culls to save the environment and want to end capitalism.
Given this is a political forum, can we at least settle on a sensible definition of 'radical' that applies to both right and left? Radical doesn't just mean advocating dor change you either misunderstand or don't agree with.
There's a pretty obvious line that defines radical as being a belief that the system cannot be reformed or gradually improved, and that it must be overthrown, broken or completely resisted or withdrawn from.
This stands in contrast to moderates who beleive that the system can be reformed or improved through existing channels - in Australia through democracy, public advocacy, even peaceful protest
Thus:
- democratic lefties want to fiz the system - more equality, animal rights, whatever, but leaving the frame the same. Radical lefties want to smash it completely.
- radical right-wing is the belief that democracy is flawed, power should be invested in inherently superior elites, often with violent suppression of dissent. Fascism is one form of this, but there's plenty of other authoritarian forms here (eg Putin).
Back to this topic, the concerning thing about Trump has always been his escalating disregard for political norms, including refusing to acknowledge the election result and the January 6th shenanigans. There is certainly a radical element to his politics - if not wanting to abolish the system, he is actively undermining it. I don't think he is a fascist - again, not all right wing authoritarians are. I do think he would wear a fascist cloak to get elected and that is just as worrying (un anprincipled authoriatarian is just as scary as a principled one)
