I would debate the “most people” part, but I guess we move in different circles. As well as the links posted by toomanypancakes, hundreds of the Guardian’s own staff signed a letter criticising its “pattern of publishing transphobic content”.

It is notorious in the trans community for having some strongly transphobic regular columnists.

If you do an online search for “guardian transphobia” you will find numerous media reports and trans people’s reddit posts about it over the years.
