To me, no.
But we're talking about the Catholic Church here, a religious organization protected by the First Amendment.
According to the Catholic Church, racism is a mortal sin and so is homosexuality.
I didn't make the rules, the Church did.
Would you prefer this example instead: 
What if I wanted to form a group which promoted abortion?  
Now, as a conservative civil libertarian, I'm pro-choice, but I don't expect the Catholic Church to support my views.
It is a private, religious institution.
