When people call US party politics “polarized”, they are obfuscation things because there is a way in which it is very false and one in which it is very true. The parties are not radicalized in opposite directions [i.e. having contrary radical views], the Dems are just Diet Republicans. They are, however, highly dogmatic [i.e. intolerant of contradiction].

.world is not radical compared to any Republican space, but it is certainly dogmatic in its “moderate” views being enforced.
