How to respond to FIL

[BasilF12]

Ok I am not unreasonable. DS is 4. Not at school yet. FIL is critical of my parenting and accusing me of making him soft. Last weekend he told DH I will "make him gay". DH told him not to be daft. Homophobia aside I am fuming at FIL for being sexist and prehistoric. We are seeing them soon and I need to know how to respond when he says this without causing WW3 (which I would happily do but DH wouldn't want this.)

Examples of me making DS "soft" include:
I don't smack ever or shout often (only to prevent danger) as it is counter productive in my eyes.
I buy DS dolls because he likes playing with them. He also plays with other toys so??
DS watches Barbie movies, because he likes them. He also likes other movies, so??
DS has fancy dress, he chose the costumes and some are dresses. (Fairy, nurse). He also has superheroes so??
DS asks me to paint his nails when I do mine and I do it.
I comfort him with cuddles if he is sad or hurt. He is sensitive, but that's just him.
I let him wear pink, or blue or whatever he chooses.
I let him have a sparkly bag because he likes it. He also had a dinosaur rucksack so??

DS also likes superheroes, he runs and climbs and likes cars as well as dolls.

I know when he starts school peer pressure may curb some things but he is 4 FFS!

So witty but not horrible comebacks needed please!

There are some fantastic responses on here but, i think fil needs 're-educating', more than witty come backs.
If you were brought up to believe something is wrong and had it drilled into you that, this thing is wrong for half of your life or, at least a good chunk of it, then suddenly the game changes and.it not wrong anymore, it's hard to change what you have been taught.
It doesnt make what he is doing/saying right but shows he is uneducated in this matter.
Unfortunately it will take years for these homophobic views to go away. I mean as recently as 30 (ish) years ago they were still committing people to asylums for being gay. You couldn't get in to he army if you were gay. There are still camps in other countries (not sure if there are any in the uk) you can send your child to to "remove the gay from them". You got beaten up for being gay, then the police would tell you it was your fault you got beaten up, because you are gay.
It is deeply ingrained (brainwashed) in him to believe that being gay is somehow wrong. There was alot of stigma for certain generations, and whilst modern society is becoming more accepting of lgbtq, certain generations need more help to understand that it is nature not nurture that 'makes' someone gay.

Just tell him you're bisexual.

The idea is from the ingrained misogyny and homophobia that women are to "blame" when something is "wrong" with their sons. Though the usual advice would be to wonder what your husband was doing about this, in this case that is counter productive. Tell him quite calmly that you and your husband will parent as you see fit. You don't have to explain or excuse your decisions on this.

“"FIL, have you noticed that it's only ever boys that get restricted in what they can't wear and play with? Girls never get told they aren't allowed to wear blue, or trousers or play with cars or swords? Why should boys not have the same rights as girls?"

Well, whatever you say, don’t say this- it’s not true!

I do find young people now that have grown up with political correctness around gender neutral toys are the generation that are most confused with gender/ and or sexuality.
Have you been in a toyshop, or the children's clothes section of a supermarket lately? Stuff is more heavily polarised into pink vs camo sludge than ever.
