This comment is an incredible thing to use as an example.
You made this comment hours and hours ago. Yet in that time, 'what is grey' has changed. Things have been voted up and down. And who's to say that 5 years from now, 10 years, the 'web theme' of this site won't change.
And then grey means something else.
Now what you've said has changed, due to how the 'culture' on this site has changed.
Meanwhile, there have been people examining comments, and actions, people made even decades ago. Comments and actions taken out of context, single sentences quoted out of paragraphs from emails/etc, and then social media destroys them without care.
Not only must people now 'clam up' against current threat, but all potential future threat. A comment well received by a friend, can 20 years later be taken out of context, that context being historical, cultural, and personal.
And on top of all of that, a friend can become an enemy 20 years later, for entirely non-sexist, just normal person-to-person reasons. People can and do change over time, sometimes not for the better.
So:
* fear what you say now
* fear the future, for people will misquote 20 years later
* fear even female friends, for some may change over
decades, and destroy you later
I don't think this is here now. But if the perception of what is happening continues much longer, it may.
Heck, I recall reading an article which coached men to "never be alone with a woman", for "she could claim anything later". This thought process makes it highly difficult to even give advice in private!
