I was asked to do a tweet on how to be a good Minceir Ally. So here are my thoughts ... Other Minceiri are welcome to add.
Allies can do the actions you can.

Learn about Traveller Culture, history and issues affecting us from us not others. You can do this by checking Traveller org websites, chat with us, invite us to give inputs in your place of work.

Educate others and challenge Anti Traveller racism when you see it.

Get to know Travellers locally and local issues. Support the work of local and national Traveller orgs.

Get to know Travellers locally becoming friends. Invite Traveller children to your parties/playdates. Let your children go to Traveller children parties,playdates in their home.
