Perhaps.
However, he it seems he is empathetic, and educated on social issues etc....
Didn't he kneel during the American national anthem a few years back to show his support against police brutality against black people? He has also educated himself on racism and social injustice in the US and spoke out along with Patrick Mahomes when so many others were staying quiet . He has spoken out to support BLM too.
I don't think it's fair to say he is 'lacking in brain cells' etc. He is informed on so many social issues and is clearly not afraid to take a stand and go against the grain -
'Kelce has used a handful of occasions to show his willingness to take stands, even if it means placing himself in the crosshairs of the US’s political right. Just weeks after American conservatives mounted a boycott against Bud Light because it published an advertisement featuring transgender social media influencer, Dylan Mulvaney, Kelce agreed to appear in a commercial for the beer maker.'
Like the singer, the Chiefs football player is at the top of his field, while his support of BLM and vaccines align with her progressive politics

To me, the above outweighs any ignorant/ misinformed comments he made at 21 years old.
