I finally understand the subs vs. dubs debate [I Like Anime]

I never really got into anime, so I had no idea, then I started watching the subtitle versions and... the majority just fit better. Then I heard about a series called Dragon Maid (?) and I thought, "Hey, that looks fun, maybe I'll buy it." Apparently the dub version changed a lot of dialogue to a bunch of sjw nonsense. Why? Why? Why ruin something? Luckily I know a guy who definitely totally didn't pirate anything because that's illegal and he would never violate the law, but he has a digital copy. It's a cute series.
