A "gender gap" exists in almost everything! This is not a bad thing, despite the claims of the idealists that strive to live in a fantasy land of their own creation. We don't live in an ideal world therefore ideal outcomes don't happen. Funny how it only becomes a bad thing when certain groups of people are deemed to be in receipt of a bum deal.
This morning I was looking into the legal requirements for bathrooms in the workplace, as part of a planning process for a new build. There is a gender gap in that too, but because it is a gap that favours women, it is seen as acceptable. Female employees have to provided with far better provision than male employees do, even down to the number of facilities provided per the number of employees.
For women only or mixed used toilets, you have to provide at a minimum 1 toilet for 5 people or fewer, where for men only you only have to provide a minimum of 1 toilet for 15 people or fewer.
I notice there aren't many people calling for discrimination to equalise this. If people were genuinely seeking equality they would be seeking to erradicate these things too, but as usual the cry for equality only comes when a person/ a group of people are seeking preferential treatment for themselves over others.
Are you actually taking the proverbial here? Let me think why there might need to be more toilets for women then men...can women use urinals? Erm...no. Go and have a word with yourself, honestly. There is little point in trying to have a discussion with someone about equal rights when they can't even understand why there should be more toilets per capita for women than for men.
