I think not really. Yes this is a BTC forum but it can still be like any other websites out there.
It is not mainstream though. Yes, it is popular but it is not like reddit or quora. Most of the people on here are ones who are already into bitcoin or would like to learn about bitcoin. I’d be surprised to see a bitcoin hater here.
I mean people can also do or use other things, except only maybe for those who are hardcore ones. They are the ones that can get biased. I think stocks and BTC are not that far from each other.
Most likely there are a lot of bitcoin investors who are also investors of stocks. Once you invest in something you are gonna want to focus on this kind of industry and might want to explore various markets.
