Every time I search something like “Why is X bad?” on reddit or other forums, the majority of comments is always people arguing the exact opposite. This has been my experience countless times over the years. Recently I started searching the opposite of what I want to know, like “Why is X good?”, and it works flawlessly.
I see it on here too. Some people really feel strongly the opposite. Some people kind of just want to be dicks.
I think it depends on how you say it. In general, I think it’s a good thing see other people’s opinion, especially if you already have a certain bias. IMHO there are very few topics that have only arguments in one direction.
