For many, sports, along with their teams they root for, is an immense passion, a way of life so to speak, borne from their own life experiences, etc.
Your post comes across, IMO, in a lecturing and condescending manner. Good for you that you don’t “personally feel bad.” Insinuating if one does feel bad in the moment, or a bit afterwards, that they need to find something else that’s “important” to them is somewhat sanctimonious.
I guess one could ask/argue why you need to use sports to “escape.” Escape from what? If your work & personal life finds you needing to take your “mind off” of those for a while, perhaps you may want to reflect upon that?
