If you want to have a private conversaion, social media doesn't seem to be a good vehicle for it. Much like airing your dirty laundry in the town square has been considered bad etiquette, airing personal greivances on the internet seems to be in poor taste.
It must be noted that manners never arise sponaniously in culture, but becuase people fear the consequences of breaching etiquette. I for one welcome the return of politeness to society.
There's a big difference between politeness and total conformity to established (by the powerful) norms. Disagreeing (politely) with government policy on a public forum could easily prevent you from obtaining certain positions or status in the future if this is an accurate trend.
Not to mention that the freedom to go outside of convention without arbitrarily large punishment is worth preserving in of itself.
