What is important here, is to understand the political orientation of these newspapers. What front do they represent, what are the policies of that front, what distinguishes it from its rivals in Iran?
Most of these are reformist papers. The stance of the reformists on Afghanistan completely differs from that of the IRGC. The IRGC has been working towards normalized relations with the Taleban for several years now. Reformists however have engaged in a huge media campaign involving personalities such as show business stars (actors etc) among others, in order to sabotage this relationship, and these reformists are advocating Iranian intervention against the Taleban. On the opposite side of Iran's political scene, activists loyal to the Recolution such as Ali Akbar Raefipour, have clearly and explicitly pronounced themselves against any sort of action against the Taleban, at least as long as the latter do not initiate hostilities.
As for the accusation of "sectarianism" in the above shared Tweet is quite misplaced I must say, given how Panjshiri Tajiks are Sunnis rather than Shias.

I agree with you on the whole. However the liberal camp (reformist / centrist) has its own supporters among the Iranian public, and if you study their activities, they are advocating intervention against the Taliban. When it comes to Palestine, Lebanon, Syria however, these same liberals want Iran to disengage ("na Lobnan, na Ghazzeh, janam fadaye Iran" being one of their favorite slogans, as you know). Connect the dots: it's a stratagem to relieve pressure on the zionist entity to Iran's west, and have Iran bogged down in Afghanistan to her east instead, which would not threaten zionists and American interests as much.
