The Chaggot stream was a lot easier because practically nothing was in dispute. There were hours of video footage of Chaggot asking random people on the street what they thought of him raping a 13 year old when he was 18. Even then, when they asked questions "off limits" about AFPAC and the $10k thing or whatever it was, it was at the very end of the stream after they already got what they wanted from him.
With Fagmenco there was a lot more in dispute, so just right off the bat, the first question being "Are you a pedophile?" and then subsequently 2 hours of "But, you're a pedophile!" was probably not the best way to handle it. They should have carefully and calmly questioned things first, and then ended with the blunt pedophile accusations. Some of the things they got wrong - like the chomo quotes not being in the group but in some other group or his profile or whatever it was - forced them to either concede or double down, and since they already declared him to be a pedophile they had no choice but to double down.
