Liberals, on a whole, are more open to creative concepts, while conservatives tend to have an intense dislike of anything, media included, that goes against traditional Judeo-Christian ideals. This leads to SJWs playing video games, and anti-SJWs not playing them.
Ironically, your use of “NPC” as an insult just serves as further proof of conservatives’ misunderstanding of video games. Although NPCs can be antagonistic, NPCs can also provide useful items or quests and give valuable support to the player. If conservatives truly appreciated video games, you would know the importance of NPCs and not view the term as inherently negative.
