Having read the double discrimination chapter of the Everyday Sexism book, some of it struck a chord with me. I haven’t experienced it personally, but these are several things I’ve come across:

-Trans women being described as ‘not real women’. At least 2 people (& people who I’d have thought would’ve known better) have said this, as have people close to me, alas. I’m not trans myself, but it still annoyed me.
-My parents referring to trans actress Laverne Cox as a ‘she-he’ after we’d watched the remake of The Rocky Horror Picture Show (for any non-Rocky Horror fans out there, or those who haven’t seen the remake, Cox played the chief part- that of Dr Frank-N-Furter- in the film).
-Someone I know saying that being trans is a ‘choice’, that it ‘isn’t normal’ & that trans people shouldn’t be allowed to have their gender reassignment surgery done on the NHS (or words to that effect).
-People (one of these being someone close to me, alas) saying that they don’t like watching 2 men kissing or whatever, but they have no problem with watching 2 girls (sic) doing this. Homophobia AND sexism there, folks.
-The notion that men can’t be both gay AND ‘macho/masculine-looking’ & that lesbians can’t be ‘conventionally’ attractive- the phrase “too pretty to be a lesbian” is a common theme, & I’ve also heard “she can’t be a lesbian- she’s pretty!”. Yet more homophobia & sexism, with a bit of stereotyping chucked in for good measure.
-I’ve mentioned before that some people seem to think that in same-sex relationships, one person is the ‘man’ & the other the ‘woman’, which is quite frankly nonsense.
-The notion that women over a certain age can’t be attractive, can’t dress a certain way, are perceived as being over the hill/old & quite simply aren’t worthy of notice. I mentioned the Facebook page entitled ‘Helen Mirren is ageing beautifully’ in a previous post under a different handle & voiced my opinion on how ridiculous it was, so I won’t repeat myself. I have heard someone say something to the effect of ‘she looked like she could’ve been a looker when she was younger’ when referring to a woman that they’d seen in the street who was presumably over 35- because OF COURSE, once a woman reaches a certain age, she can’t be seen as being attractive any more! The notion of women being ‘old’ once they hit 40 was also used as a means of humour in the sitcom Birds of a Feather, with much of the humour centring around holding the character Dorien Green up for ridicule for being ‘old’, dressed in clothes that were ‘inappropriate’ for her ‘age’ & looked like ‘mutton dressed as lamb’.
-I used to watch the TV show Diagnosis Murder a lot, & I started to notice towards the end of my time watching it that there was quite a bit of sexism & racism in it. People of colour didn’t appear that much, & when they did, they were usually portrayed either as the villains or in servile roles like maids. Women were also portrayed negatively, as either the villains, the victims or as hard, bolshy bitches who’d sell their own grandmothers if there was something in it for them (ambitious career women were usually portrayed in this way.
