Man I can translate what she said to u and explain all the situation. (it involves politics in Brazil)
But only if u really want, like a friend.
In summary, she said that she doesnt give a shit if he posts this in other posts, she thought it was very serious and she didn't receive this well. Man, in my opinion, u are right, Xeppa isn't racism and she is overreacting the situation, but he took a risky position to post this photo, she's not wrong to blame him because it's a very interpretable photo, it's like call a friend of you by "viado" in Brazil, it may be considered against lgbt, but in some regions not.
Man, we are taking this to another level, I noticed that u dont have bad intentions, but we are discussing a lot here. We need to get out of twitter and take this situation with a better mental health.
A hug from Brazil and hope this ends as soon as possible in the best way.
