Social media does seem to foster cheap and nasty 'gotcha!' trolling as opposed to constructive debate and reasoned contest of ideas.

Here on SNs its not as bad as some other sites but still often difficult to have a constructive debate.

More commonly here it tends to be a Libertarian circle jerk echo chamber where any alternative viewpoints are either ignored or shouted down with shoot the messenger name calling avoidance of the issues.

Libertarians have sometimes complained nobody is prepared to engage with them in reasoned debate, but when such opportunities are presented to them they so often fail to respond in a reasoned manner.
