Seems Maher is enduring a bit of a backlash in some quarters for apparently stoking Milo's ego by taking him onto his show.
Apparently it's got something to do with Maher calling trans people "weirdos".
I think there are two big takeaways from that:
1. Maher didn't need to take Milo on for every thing he said (and i think it's good that he didn't), but he didn't need to be quite as chummy to him even if the plan was to deny him of the offense he craves (which happened)
2. Taken away from his immature base, Milo looks like a fucking clown. Sunlight is a very good disinfectant.
