Yep, because other incredibly popular global sports like basketball, soccer, golf, and tennis are all known for their violence. Sports couldn't possibly be exciting or draw a crowd without brain damaging collisions.
The CTE link is of course not definitive at this point because it doesn't have decades of study behind it, but the results so far are astonishing. If you can live with yourself by saying, "who cares if these people permanently damage their lives and families, I need something to amuse myself for a few hours per week. They shouldn't try making the game more safe because I might have to adapt my taste in sports." then I guess we have two different definitions of humanity.

91% of the donated college players (48/53), 56% severe CTE
99% of the donated NFL players (110/111), 86% severe CTE
The test is only about 10% of former NFL players that have died since they began the study, so even if the other 90% that didn't have their brains donated were clear of CTE, then it still means roughly 10% of NFL players develop the condition.
The study is biased because the brains had to be donated, but so far there has not been any tests that suggest the opposite.
