I would value other peoples opinions and essentially how to manage this behaviour and situation.
We have a family what’s app group that includes an elderly grandparent.
Both my dm and Auntie (dm’s sister) have recently been posting things in the family group chat that are questionable and it’s blown up because I’ve called them out on it.
I find their posts antagonist and to be honest just nasty behaviour but I’d like to see what others think - they’ve said I’m stopping their free speech and they’ve had enough of my patronising drivel! Oh and I have no sense of humour 
Some examples are:
On Saturday from Aunt “looks like you’ll have to get your Covid jab done soon GoddessKali or they won’t let you in!”
Referring to me moving to an EU country in a few months. I respond that no, I won’t be getting the jab and that you only need a negative test to enter and Aunt responds “looks like you’re limited to the UK then, Blackpool is nice 🤔”
I’ve never discussed vax with her, so my ‘d’m has obviously been gossiping and ‘d’aunt tried to shame me in front of the whole family. If she had any concerns for my welfare message me directly?
Then this week with the whole M&H I’ve had Facebook discussions with both dm and Auntie in that I’ve been posting that Mental Health matters, we can’t rip someone to shreds like this and that our newspapers have created a hate campaign.
Whereas their view is they’re spoilt entitled idiots and God save the Queen.
I don’t have a problem with our FB discussions or that we disagree....
However they’ve now started posting anti M&H posts and meme’s in the what’s app group (knowing my feelings having discussed on FB this week!) which have included them saying ‘she should be muzzled’ and ‘I’d like to see the pair of their heads on Tower Bridge’.
When they’ve been called out on it, it’s apparently ‘dark humour’?
Other relevant facts:
My dm is one of those people that says ‘I’m not racist but......
I don’t want you having children with a black man because they’ll be teased and bullied
In my day only the sluts went with black men
And other such nuggets! 
The rest of the family have been supportive and sent messages about establishing boundaries and it’s ok to feel offended by something and people have to respect that etc. However DM and Auntie are adamant they’ve done nothing wrong.
Oh and no one else posts anything like this, it’s either harmless jokes or kiddie pics etc.
The final straw that blew everything up was this last message I’ve attached a photo of. She knows I can’t even wear jumpers that have a tight neck, necklaces. Anything that’s on or near my face / neck gives me panic attacks and earlier this year when pregnant I fainted, only for a few seconds but enough that I lost my balance and couldn’t stand / walk etc.
Any ideas how to unpick this mess?!
For me, it triggers this childhood emotion of being picked up and hanged up on. Because I don’t agree with their view point they keep point scoring and attacking. Can other people see this or am I being over sensitive?
