Maybe you should practice saying that you did something because you wanted to. Or, “the women marched because they felt they had good reason to.”
The other women should not have said that women shouldn’t have marched.
Of course, when people march because Mr Trump made them mad, they probably shouldn’t call it the March for women.
Personally, I just don’t like protests, but this one was, by far, the least offensive protest I can think of in recent memory.
