In fairness, I’ve met several people online, even a few on this site with similar mental problems actually… So some do tend to overreact over things, due to bad past experiences.
I’ve actually been attacked by Sony fanboys for liking Nintendo, as well, (I even got attacked for liking Sega’s Sonic series, as well) so it’s a li’l understandable why some Nintendo fans would develop a bit of a persecution complex.
I used to be afraid to admit I was a Nintendo fan at school, or online, as well, until the fanboyness cooled down online, and people started to see loyalists as annoying, as well.
Plus with things like Nintendo being ignored on some game sites, (some not regarding WiiU or 3DS as legit consoles during the WiiU era) alot of Youtubers being rather critical of Nintendo recently, (whether they deserve it, or not) drama over things like Switch Online, (and people bashing the NES games especially) and stuff like third-party games being released on literally every system, but the Nintendo one, (“Disney Afternoon Collection” a compilation of NES games being the worst offender of this) it’s honestly understandable why some loyal Nintendo fans are getting a tad touchy…
I’ll even admit, I’m a li’l tired of that stuff, but overall Nintendo feels like the “Disney” of the Gaming industry, as they’re both widely loved, and hated at the same time.
