I'm not against republicanism. Your example, 'Great time to abolish the monarchy. Monarchies are fucking stupid', is not an interesting or well though-out comment. If that's all the effort this commenter felt like giving to this forum, then it should be down-voted.
A lot of us here are coders and we appreciate concise code. Why not, then, concise arguments? Bias wrapped in fake nuance is obvious and time-wasting. "Fucking stupid" is an apt description of monarchism in this day and age.
