On Thursday, Chris Hemsworth took to Instagram to post his solidarity with the Standing Rock pipeline protest, and he also called himself out on cultural appropriation.

“I would also like to take this opportunity to raise something that has been bothering me for sometime. Last New Year’s Eve I was at a ‘Lone Ranger’ themed party where some of us, myself included, wore the traditional dress of First Nations people. I was stupidly unaware of the offence this may have caused and the sensitivity around this issue. I sincerely and unreservedly apologise to all First Nations people for this thoughtless action,” Hemsworth wrote.

The apology was made in the caption of an image of himself in Thor attire standing with director Taika Waititi and holding up a sign that reads “We stand with Standing Rock.”

Standing with those who are fighting to protect their sacred land and water. #nodapl #waterislife #mniwiconi @taikawaititi I would also like to take this opportunity to raise something that has been bothering me for sometime. Last New Year's Eve I was at a "Lone Ranger" themed party where some of us, myself included, wore the traditional dress of First Nations people. I was stupidly unaware of the offence this may have caused and the sensitivity around this issue. I sincerely and unreservedly apologise to all First Nations people for this thoughtless action. I now appreciate that there is a great need for a deeper understanding of the complex and extensive issues facing indigenous communities. I hope that in highlighting my own ignorance I can help in some small way.
