The 8 groups of colors you see on the graph are actually dozens and dozens of parties who group themselves into more compact coalitions depending on their broad ideology. This is actually no issue to get shit done and pass plenty of legislation.

What we actually don't like is that the far right groups (Conservatives and Reformists, and Identity and Democracy, and a third secret option) are growing even a little bit more, which increases the possibility of them actually passing the laws they want.

It's far from perfect, but the European parliament is vastly more functional than the American Congress, just based on the amount of legislation that is crafted, compromised on, and passed. These laws, which have to be adopted by all the countries in the EU, are the most prosocial and environmental in the world.

With these elections increasing the size of conservative coalitions, there will be more of a push against things like green regulations, immigration quotas, and support for Ukraine.

More conservatives are being elected because right-wing nationalist/populist parties across Europe are fanning the flames of anti-immigrant hate, the burden of inflation, and EU regulations that might squeeze the ability of farmers (or other laborers) to make a profit, in order to sell their Make (insert country name here) Great Again rhetoric and whatever religious/corporate/fascist power dynamics that rhetoric conceals.
