I can’t disagree. But as one facet among others, I also think “concern” is reasonably warranted in conducting a comparative assessment.

Edit: also worth highlighting: “there’s nothing wrong with being against gay marriage because it’s a political opinion” is certifiably homophobic. How much responsibility Kagi’s moderators bear for not removing that comment or otherwise explicitly advising that homophobia won’t be tolerated is debatable, but it’s not great.
