Look, I hear ya' and agree with you're basic premise, but I do think you're being a bit naive about the whole situation. The level of nastiness we're witnessing towards Red isn't happening in a vacuum - look around at social media when it comes to politics, sports, entertainment, etc. This is just a carry-over of the toxic climate in general- it's why haters rule the roost.
Fans, whether SU or otherwise, have ALWAYS veered towards assholic behavior. I remember JB getting pummeled relentlessly because he "cant coach & can't win the big one"- all pronouncements by misinformed, entitled fans who couldn't coach a peewee team, but swore they knew more than the HC. It was only when the wins piled up and it became obvious when the negatoids stepped back, and of course the new line of attack evolved into "he stacked his wins record w/ cupcakes" blah blah blah.
It's simply the nature of the beast, amplified 10000x in our current media environment.
As one medical professional to another, I recommend avoiding meathead message boards, podcasts, and any other outlet that caters to negativity...which basically means about 95% of them. Let the patients congregate amongst themselves- its a lot healthier for you and your overall well-being. You're welcome!
