Funny, I did a college term paper on Tchaikovsky in 1975 and at the time, had no clue he was gay.
As a composer, he also used to score a lot.
Is it known for sure that Tchaikovsky was “gay” or is that just a rumor? Some people have peddled the notion that Abraham Lincoln (father of four) was a homosexual based on pretty flimsy evidence (enough to satisfy the Log Cabin Republicans) but I think that is only accepted by those wanting to push the gay agenda.
Are you sure he was gay? If gay people are to be believed, every person who did something noteworthy in history was gay.
