I don't see much reason to change it. I've never given any angry reactions, and have only received one or two. Axes, boulders, and gravestones are much more common, and I have accumulated my fair share. But, if I'm being honest, I was never taken aback when I received them. I expected people to disagree with me, I expected people to have differing viewpoints, I expected people to react, because everyone does. Sure, it would be weird if I got an angry for saying I killed the Moonlord, or someone axed one of my builds, but it wouldn't hurt my feelings. And if you react with an angry to any of my multitude of opinions, I wouldn't feel any different. Yes, maybe it would be more constructive to voice your opinion and leave a post, but I hardly ever see anyone react without later leaving a post. In the end, people are going to get upset regardless, if we remove the reaction they'll just write a comment instead.
