My husband has been getting deeper and deeper into political conspiracies

I need prayer for my marriage. My husband has been getting deeper and deeper into political conspiracies, and it affects the way that he thinks and talks about those he disagrees with politically. He is a strong Christian and feels righteous in his opinions, but the way that he talks about those on the opposite side is becoming increasingly hate-filled and not glorifying to Jesus. It makes me feel very distant from him and very grieved. He seems blinded and it feels like he thrives on vilifying those he doesn’t agree with. It worries me.
