He was 69 and a Catholic so isn't exactly a big shock that he would have these views.He didn't just vote against gay marriage, he voted against allowing homosexual couples the same adoption rights as heterosexual couples, he voted against giving homosexuals the same age of consent as heterosexuals. So his votes weren't just about gay marriage.
I've also provided multiple other examples of morally wrong voting choices he has made as well. These voting choices are there for all to see online.
Shall we talk about the views against homosexuals in Somalia? It's illegal and punishable by death. If you are genuinely concerned about people adopting views against the rights of gay people then surely a good start would be not to mass import people with these views already in place? That seems entirely reasonable and pragmatic.
