Unfortunately, it's practically impossible to find real individuals discussing things via Google. It's all promoted content and blogspam.
A long time ago, Google used to have a filter you could select for "forums". Once that disappeared, we had the "+reddit" hack. Now what? I have no idea.
My recollection is that during the Google+ period, Google changed their indexing and basically destroyed every other forum. Things that were first page results dropped out completely and lost virtually all of their ad revenue.
