The view of Antifa will vary from the perspective of European Antifa groups, some are good, some are bad. It's not as simple as it is in the U.S so you will get varying ranges of opinions concerning Antifa. Europe has a lot more active left political ideologies and its representative in Antifa groups as well as party levels, not all left ideologies are necessarily good.
The idea that Antifa groups are automatically good because they oppose fascism is false, there are Antifa groups that don't give a shit about particular social issues and are authoritarian and hostile even against people who aren't nazis, none are automatically good, some of them don't give a shit about social issues right now because issues such as racism are viewed in a very one dimensional manner, the only goal is economic justice because traditional left politics is about achieving social justice through economic justice, so many issues of racism for example is swept under the rug because it's not important because it is believed it'll be solved later through proper means (i.e like economic). That's why a lot of PoC in Europe don't always like some left parties in their country as well.
There are antifa groups in Europe that are filled with people that believe in totalitarianism and support ideologies such as Stalinism, it's a lot more nuanced, it's not just about opposition to neo-nazis, there is a lot of destructive ideology within too. Many hate and oppose the EU, this is something that far-left and far-right have in common. If you look at even the most recent protests in Hamburg the core part of the protest was anti-globalism.
In Germany we have Antifa groups who have a fetish over the Stasi and KGB for example. Just because they fight nazis doesn't always make them good. Hell there's even RAF sympathisers, a former straight up far-left terrorist group in Germany.
Even on a party level, Linkspartei is utter shit in Germany, they may not be Nazis like NPD/AfD, but in no fucking way do I think they are "good" or "better" just because they are far-left and not Nazis.
European anti-fascism is primarily rooted in anti-capitalist (considered a leading factor of the emergence of fascism) as well as anti-American (being the face of capitalism in the world). Many people in Antifa groups here absolutely despise the U.S and also why they like the Kremlin because they're perceived as the only ones who seemingly stand against the U.S, it's also why Linkspartei is pro-Kremlin and why they try to appeal to these groups as well.
Nazism is totalitarian, and so is things like Stalinism or Marxism–Leninism. It's still totalitarian whether it's on the right of left spectrum, this is evident in right and left groups in Europe, it's not always just because they're leftist that they are better, it's a very juvenile view.
Antifa groups in Europe are decentralised, there is no common identity, no common name for each group, each country varies and it varies within the regions of the countries too. Its views vary, some may be a great fit, some may just be a bunch of stalinist fuckers. It's not all the same.
