That doesn't have anything to do with her criticism of Loop Quantum Gravity, and is precisely the derailing of the topic that dang is asking you to avoid.
When people don’t have expertise in an area they are prone to making really dumb comments. She has a history of this on other topics. As such I think it’s appropriate to mention so that people can evaluate how much weight/time they want to spend on her video and views.
Do you have expertise in the area of deciding source trustworthiness or relevancy in certain fields?
I do not. I do have a sense of the notion and make decisions for myself on whether or not something is worth my time. While her video might be accurate in this case her past casts doubt in my mind and as such I’ve decided not to watch it. Other people might find it useful to know about her past errors when deciding whether or not to watch this video.
