Actually on the Andrew Bolt anti-same sex marriage thing, he says he sided with the anti side because the proponents of SSM haven't upheld "civil discourse". I decided to look into it a little to see what people were so angry about.

So that's the polite political discourse on SSM that Andrew Bolt sides with. This should give you an idea why people don't especially like Andrew Bolt.
Another thing is that he's a hardline historical revisionist / denier about the genocide of the Australian native population.

Whites aren’t making Aboriginal women 34 times more likely to be hospitalised by their men.
Whites aren’t making Aboriginal children five times more likely to be hospitalised after an assault, or nearly 10 times more likely to need removal from their dangerous homes.
Whites aren’t making many Aborigines out bush choose to live where there are no jobs.
Asshole ... we
kicked them off all the good land now the only land that's left to them is the shitty scrub. Then we didn't provide infrastructure for them. It's their
homeland. It is in fact our fault as a nation that we didn't spend any money to develop livable standards for the remote parts of the nation that have black people there. You should see how much money they spend ensuring that rural white people have services.
Another thing he's big on is denying that the Stolen Generations ever occured. It was an era in which official policy was to remove any mixed race aboriginal children from parents and place them with white families, the idea was that blackness would be bred out. A small number of revisionists claim it never happened (despite a fair amount of insider documentary evidence) and that any removals were merely warm hearted attempts to save children from their evil abusive black parents.
