I take it that, somewhere on Tumblr, this issue has exploded in an entirely unintended direction. I was not talking about passing judgment on people. I was talking about making yourself happy and comfortable in your own space.
The point is that some people get upset by, say, Mary-hate, or Mary-love, or the johnlock conspiracy, or disbelief in the johnlock conspiracy, or toplock, or bottomlock, or spiders, or aggressive social justice posts.
And your Tumblr dashboard is your own space. So if the things that show up on it upset you, then the thing to do is to use the tools at hand to rearrange the people and topics that show up on your Tumblr dash so that it ceases to upset you.
