It is not enough to sit on facebook and twitter and other social media and indicate your thoughts and prayers, to use the appropriate hashtags, and to follow the moral outrages of the day. You will get a dopamine hit from likes and retweets, but nothing will change.
To change you have to act. On yourself: on others. It is hard enough to change yourself: it is much harder to motivate others. And if you are motivating others without a lived experience of struggle and change, others will know.
Real activism hurts.
For real activism involves working with people, and people are not their instagram or facebook feeds (Nor should they be: only a fool trusts social media).
Now, some of us are paid to do this kind of work, and in my society that leads to people thinking that they are entitled to whatever they want. Others work through the church, and part of that is simple, practical care. Some of us find ourselves on committees, and have to tone down what we are thinking and speak weasel -- that language loved by bureaucrats, executive officers, journalists and politicians -- which is orthogonal to reality, but the only language they understand.
Some confuse being kind with agreement. I can disapprove of what someone does and still help them. Indeed, our duty is to help those we disapprove of, because if we decided that we were only going to be in a club of the righteous we would be thrown out ourselves.
One more note. Doing good with people who are broken, scarred, and often not that particularly nice, drains you. For some, it is our calling, our vocation. We meet on Sunday to worship God, true, but also to encourage others and ourselves to keep on doing that which we ought.
Then we rest. We need time to recover. We need to look after ourselves. Real activism is not a hashtag. It is a calling, a life work. Which we do not to show our virtue, but to help.
The virtue signallers get in the way. Do not be them. Do not be like them.
