By their own overinflated count homosexuals only comprise 10% of the population, this means that heterosexuality IS THE NORM.
I note that hatred and injustice against religion and religious believers is just fine...
Heterosexism is defined as a "prejudice against homosexuals on the assumption that heterosexuality is the norm".
It is the norm, both biologically and socially, and people should have a right to believe in facts and in their own moral tradition, and not be forced to believe some leftist gay activist's fantasy world and ideology.
