i think everyone shows support in their own way, and not everyone has to be like you to be a true loyal fan.
No true Scotsman, or appeal to purity, is an informal fallacy in which one attempts to protect their universal generalization from a falsifying counterexample by excluding the counterexample improperly.[1][2][3] Rather than abandoning the falsified universal generalization or providing evidence that would disqualify the falsifying counterexample, a slightly modified generalization is constructed ad-hoc to definitionally exclude the undesirable specific case and counterexamples like it by appeal to rhetoric.[4] This rhetoric takes the form of emotionally charged but nonsubstantive purity platitudes such as "true", "pure", "genuine", "authentic", "real", etc.[2][5]
you also don't know whether those guys would keep the damwon flair or not. plus with how flairs work on vlr you can only put on one flair. maybe some people prefer different flairs to others. as long as they are still supporting those teams why should the flair itself matter?
