"Rethink your life choices" — because they have opinions that are unpopular and they express them anyway? I might not agree with those opinions, but I fail to see how discouraging them from expressing them is in any way good.

People expressing unpopular opinions and defending them with evidence is how we find out when the popular opinion is wrong, and how, when our discourse is functioning properly, we can gradually change the popular opinion to be less wrong. You, and the people downvoting the comment, are throwing a monkey wrench in those works.
