There are plenty of reason to take issue with the source material, but the specific issue was with Last of Us 2.
For the record, the so called incels absolutely loved the first game.
You had an entire game based around a man whose world crumbled around him when his daughter and wife died. He continued finding a way to survive in a zombie infested world. Not shockingly after losing his family and in a zombie world be became hard, jaded and was more than a little vicious.
For complex reasons he was entrusted with the life of a young girl, in fact saved her life. The woman who encouraged him died. He was left alone with a girl who was about the age of his daughter when she died.
Though it wasn't well painted in the TV series, Joel was gruff and offish early given his past. Over time, through lots of life threatening moments, he and Ellie slowly developed a stronger and stronger bond. She started really listening and respecting him and his heart opened up. He was healing. It was amazing to see the development. It was what was truly loved about the game. Her growing under his protection and him healing through her.
Then in the second game, early in, he's killed. Bam!
But yeah, its all because she was gay and every person that played the second game and didn't like it because they are incels.
Get new material. That line of bullshit is tired.
