Since posting things online is an entirely useless and ineffective form of activism, when you post such a statement, it has absolutely no effect on me.
And I don't even get to see your words of wisdom either, so I don't even get to know such a theory, because posting online is worthless.
To make sure I know how useless keyboard activism is, you have to meet me in person in real life and scream it into my face. Only then I will receive the message and be able to act upon it.
So until then ... I'll be waiting.
