two great articles:

1) Problems with the ABI (one of the most widely-used tools to measure sexism is the Ambivalent Sexism Inventory)

https://becauseits2015.wordpress.com/2017/09/17/problems-with-the-standard-tool-for-measuring-sexism-the-ambivalent-sexism-inventory/

2) The problem with trickle down equality - framing mens issues [e.g. conscription, draft, educational attainment, homelessness, suicide rates] as really being due to sexism against women, and women as main victims of these things.

3) The problem "Gender" Equality Index - the one used by UN, WHO, countlessly (hundreds of thousands of times) referenced by governments, charaties, media.... i say "gender" as it literally does not measure gender equality. It measures women in certain context and does not measure male disadvantage in any way (and even counts it as full equality e.g. men have to die 6% earlier than women in every country, if they only die 5% earlier than it is counted as sexism against women 100% women in education = full gender parity 51% men = sexism)
