Virtue signalling gone wrong for poor old Manly.
These type of gestures for such a complex situation are fraught with risk, as they've just found out. In reality, Manly stood to gain very little by doing the pride shirt (maybe a few shirt sales, but the gay community are hardly going to decide to all become club members because they wore a pride shirt), but they have now caused an uncomfortable situation within their club, and media pressure on their organisation, particularly certain sections - these players will be under intense scrutiny now.
They'd have been better just promoting themselves as entirely inclusive without forcing anything on to the players - they should have known this could cause issue, the Izzy Folau situation should have taught them that. Those players and their religious beliefs are entitled to the same protection and inclusively as the whole LGBTQ folk (whether you agree with their stance or not), but they've just been thrown under a bus (a big politically charged one at that) by their club.
This is wonderful.
