I had met Serajul Alam Khan not once but multiple times in social settings. He could be a thinker BUT for all evil reasons one can imagine. He tried to orchestrate many things much of it turned into failure and left Bangladesh with trail of destruction. His brand of thinking very much aligned with indian hegemonic design and "anti Muslim" agenda and often at the end fruits are hijacked by indians. His lastest visible project was 1/11 when army took over power under cover of interim regime and false UN letter. Culprit general Moeen U Ahmed was one of Serajul Alam Khan followers. But at the end indians hijacked his plot through US channel.
Leftists had and has influential infiltration in Bangladeshi media, civil society and even in army. Nurul Kabir, Motiur Rahman are few to name in the media. In Awami League Motia, Lenin, Inu and many other leftists are making policies.
Leftists who are predominantly against Islamic faith has no acceptability within mass Bangladeshi population. BUT "anti Muslim" platform is where india and Serajul Alam Khan theory and handy work converges.
Because of mass rejection his plots never been successful. Leftists according to his plan infiltrated in all the influential corridors including two main political parties of Bangladesh - BNP and Awami League. In one end, these leftists influenced Awami League to take extreme genocidal act against majority Muslims and on the other end, joint leftist/indian nexus kept main opposition inactive and not responding to popular demand of leadership.
Leftists became vital assets for indian design to kick off hatred against Muslim, impose hindu supremacy under guise of "secularism". But people are more aware of leftist infiltration and trick more than anytime before.
