Its nothing to do with not liking the discussion. People who have no idea about the research done in to homelessness, have not spoken to hundreds of homeless people or worked in support services to actually genuinely know about the situation are just causing more issues and hindering progress. Rough sleeping has been a thing as long as humans have been on the earth, and uninformed people just seem to think its a money issue or there is some other simple solution that lazy governments aren't doing. If the solution was a simple one of money in the right place it would have been solved years ago. The situation is infinitely more complex than that. Every persons story, reasons, and attitude to help are completely different.
Feel free to have your open forum discussion, but as proven thousands of times before this uninformed discussion does nothing other than to cause arguments through unnecessary tension and hostility. This is a problem for very experienced people to work on, not for common people with no real life experience to throw comments on a public forum about.
