It's not likely to have an impact on you because you aren't a creepy guy or a woman who has been harassed. I'm not sure if it makes a difference on a bigger scale but I know that it does make a difference to individuals. Sometimes talking about this stuff opens up a conversation off the internet as well. Sometimes being able to share something like that in even the vaguest details is incredibly cathartic especially for women who have struggled to even put words to what happened to them. It's common to jump back and forth between knowing you were assaulted and thinking you're just overreacting because others had it worse. So putting a statement like that out can mean a lot to individual women and it can mean a lot to the woman who resonates with it when the post has some more detail.
