You could have told me this is is the current layout of Israel's Knesset and I would have believed you.
Proportional representation only looks good from the perspective of a spreadsheet. As soon as power dynamics enters the picture it doesn't look so good anymore.
The biggest problem with "first past the post" is the name. Politics works when people are able to compromise. Requiring that a representative is at least able to compromise enough to get the majority of votes in their community is useful for weeding out the weirdos who are incapable of compromise. Any democracy can become two wolves and a lamb voting on what to have for dinner, but in a proportional representation this result is significantly more likely. There's no one in a the "Identity and Democracy" that has to compromise to get a few more votes to get past that post, right? Just as the Left and Green parties can have 100% uncompromising dedication to the causes they care about, so can the other side. And if that side forms a coalition, the concerns of minorities won't be addressed as minorities have zero power when not in the coalition.
Well, you never know... whatever coalition that forms after you vote might not be be as extreme right as the one that formed in Israel. Cross your fingers, and hope for a good outcome from the backroom deals to form a coalition that you have no say over. And if the worst happens and you have a far right coalition running the EU, at least the numbers line up on the spreadsheet and you got to vote for a niche party that didn't have to compromise!
