It's a good training ground to learn to control yourself for sure. But as soon as there's filtering and up- / down-voting, you'll quickly learn that none of that matters. I tried to engage in some Reddit discussions regarding politics in my country, and as soon as you don't follow the general sentiment, you get downvoted and eventually banned. Even if you're absolutely sincere and have good arguments as to why you think like this, you'll just get labelled a troll for disagreeing with something. While it's very frustrating, it's also truly scary, they just end up creating their own echo chambers, only allowing people who agree with them to post or comment. Eventually this moves on to the real world where they'll assume everyone has the same opinion because they've been living in an echo chamber.
