Fact: I had nothing at all to do with Shakespeare or his wonderful plays.
You see, William Shakespeare was born before I was. Heck, he even died before I was born. A few hours of hard work will result in iron-clad proofs of my non-involvement*. To my mind, pride ought to result from your accomplishments, not accomplishments completely unrelated to you. Or, for that matter, basic, bodily functions like which sex you prefer. Holding a parade for yourselves because you like this instead of that is like holding a parade because you sneezed without decapitating yourself. But I digress.
I figure I can have pride in myself and my descendants, to the extent that I can show some cause and effect relationship with their achievements. If I take pride in something I didn't do, I'm just a leech. William Shakespeare was a genius, but I don't see why I ought to be proud of him or anyone else of his race who isn't somehow connected to me.
I think Fats Waller was a genius, too and I don't have pride in him, either.
* - These proofs will involve logic, which as we all know, is cis-normative, patriarchal and oppressive. Sadly, I don't think there's much to be done about this.
