I have name changed for this as posted lots about my life/job etc under my other name.
This might be long as I don't want to drip feed.
My PILs and I don't really get on, it's always been a bit strained but almost 5yrs ago there was a massive row and things have never really recovered. My MIL in particular had very extreme views and I have had to tell her multiple times to please keep her thoughts/opinions to herself when they may upset others.
My husband, our children (6&4 boys) live approx 3 hrs from them so we only have to see them once a year (although they do not work they don't wish to come anymore than this and although this upsets my husband as I think he'd like them more involved he's settled for weekly Skype calls)
My four year old son, since the summer has been very interested in "beautiful twirly whirly dresses" unicorns, sparkles, glitter, hairclips etc (things that are stereotypical of little girls) myself and my husband have not discouraged or encouraged this, we have simply given him a choice, just as we do his older brother and he has consistently chosen from the girls section rather than the boys. No issues throughout the summer, he wore dresses with shorts underneath and all was well. My husband got very worried when we went into preschool that either he or his elder brother would be teased if he wore a dress so (as a compromise - to show I respect my husbands opinion even if I don't agree! Very happy for my son to wear a dress every day if he wants!) we tried to encourage him to save his beautiful dresses for home "so they wouldn't get messy" but let him have free rein on what he wears otherwise (unicorn jeans and teeshirt for example!)
During one of the weekly Skype calls today, MIL went on and on and ON about my son who was wearing a dress and even started calling him the female version of his name. My husband has asked her to stop repeatedly but she carried on, I got involved and told her to STOP BEING UNKIND NOW or stop phoning as she wasn't being fair, he is only 4yrs old! Then she stormed off and left FIL on the phone! My little boy was nearly in tears saying to me "why are Grandma and Grandad being mean to me? About my beautiful dress?" My elder one was comforting him saying "Don't worry X, just come and play with me if they're being mean. If you love it, you wear it. You look great!" Honestly, it nearly broke my heart to hear that!
So, where do I go from here? I know she will expect me to apologise, but I am not going to! How dare she say things like "she'll make him gay" and "oh X! Why have you got a silly dress on for!"🤬🤬🤬🤬🤬
