These men are leading other men to hellfire, by acting like there are no modesty rules for men.
They don't even teach their sons to cover up their awrah.
We keep seeing Muslim men pose half-naked online, some of them even have the audacity to wear pants that highlight their private parts. They also wear clothes that cling onto them like clingfilm.
Can you even tell which man is Muslim or non-Muslim in public? You can't, except for the select few who bother to look for dress-code rules for Muslim men.
