Austria doesn’t have an extremist government
Sure, but Kickl almost came to power in large part as a result of general dissatisfaction with politics in Austrai because... You guessed it, PR leads to not particularly effective government.
Israel’s democracy is flawed as the foundation of the country is dubious.
You can disagree with the creation of Israel etc but I fail to see how that means that we don't have to pay attention to their experience with PR.
Poland’s culture on issues is different
So the Polish culture is just inherently racist and tends to autocracy? I really hate this line of argument, it's the same sort of stuff that has been historically used dismiss the humanity of Black and Indigenous people.
If the majority of the people want fascism it’s going to happen in any electoral system,
Not saying FPTP is perfect. 2 party systems tend not to be great either. That's why I'm really happy that Canada has a wide mix, from NDP to the Bloc, to the Conservatives.
You also conveniently left out Norway, Ireland, Denmark, Switzerland
Yes... And you haven't pointed out all the successful countries that use FPTP, or do you really think there are no successful countries with FPTP?
Great question! In the very short term, sort of. (Though from the start I'd point out that it is much harder to envision a party like the AFD gaining traction in an FPTP system)
PR causes 2 different styles of issues with the AFD. 1) It makes politics much less likely to produce significant or helpful change, so people don't see meaningful political improvements in their lives and are more likely to turn to extremist parties like the AFD. and 2) Because the AFD has so many seats, the winning coalition has to be super broad, basically the same coalition of the Conservative and Progressives that was seen as ineffectual the last time around. Admittedly, this time they can exclude the Greens. The same reasons the previous government collapsed and led to such a significant rise in support for the AFD are still in effect.
