As much as I personally find this ridiculous, Saeed Anwar has every right to do so.
Even in the west, a few concerts/festivals have been organized where no males have been allowed and a few traditional Jewish synagogues have seperate rooms for males and females.
It’s not separation in terms of sitting arrangements bro, it’s discrimination in terms of gender - women are considered inferior to men and not encouraged to decision making, or other “manly” tasks.
In Islam, there is only one issue where females are not considered equal (as far I know) - Islam doesn’t suggest Women leadership of a nation or society. But, after 30 years of Bangladesh under two ladies; my respect for the Prophet (PBUH) and his visions have grown further - He somehow must had visualised Bangladesh under Khaleda- Hasina 1400 years back!!!!!!
