You want my thoughts?
I don't think it's appropriate or accurate.
I don't know if you've watched the women's game much but you are far more likely to see Christiano Ronaldo hit the deck under no contact than you are Amy Morgan, so how does 'she fell over' make any sense? That chant suggests the likes of Sarah Gregorious are weaker people and/or more likely to feign an injury in a game of football which is quite clearly not the case. Pretty sure in a tackle she'd break both my legs.
Further to that people should be able to offer that view without a pile of whataboutery and allegations of 'political correctness'. It's not political it's just respectful. Times change, it's not the 1950s anymore or the 1980s English terraces. The chant is embarrassing for it's sexism and for it's inaccuracy.
It may not stop happening on our terraces but offering an opinion that it doesn't seem right deserves more than the tired responses and maybe some informed and thoughtful debate.
Screaming political correctness and showing a lack of understanding about other peoples opinions or beliefs has caused enough codery in this world.
