I don't think there were any rude responses here. Some might have been shorter than others, but all trying to respond and help. Hopefully you got what you needed to get started on prop balancing, it was a good question since the Solo video quality is very dependent on eliminating as many of the vibration sources as possible. There are other areas to check/eliminate or attenuate vibration, but the props are low-hanging fruit.
MD nobody is cutting any slack these days... Hard to give good advice and be politically correct. I was on another post where the guy flew into the house and we both gave similar advice, but even though you formed your response as a question he was offended that he thought you said he lacked experience (or similar) and you had made assumptions (good ones at that) because he didn't give any specific information. I looked around at some other posts, he had already crashed once before, was on his second Solo and has only been flying since mid October. So he DIDNT have any stick time to speak of on SOLO specifically and admittedly said he panicked on both crashes/got disoriented. But he tried to come off as an "Expert" flyer. That speaks so much of someone who hasn't practiced manual flight, or has very little specific stick time on a SOLO, but he spent an awful lot of time trying to ream you in his response, even though you were dead nuts correct. We can try to help, I agree, but I'm with you sometimes there are a bunch of YouTube videos that answer a lot of these questions way better than it can be explained. Best we can do is point someone in the right direction.
It doesn't pay to be thin-skinned on any social media these days. Take everything with a grain of salt, ask the responder if that's what his intent was before reacting, being humble and asking more questions is a good thing. I like this forum because there is a lot of good information and experience amongst the population, just remember to put your filters on before you read it all.
