Assuming that you are trolling, one advice in this situation is that you can curb the urge to post something on your phone, which restricted your flexibility and causes the tendance to post things with little context and concrete meaning, and wait until you have access to the right tool for expressing yourself.

It is not easy.

At the spot of seeing something that you feel strongly, it's an exercise of strong will to actually have a clear mind and use rationality to communicate.

Emotion is the fuel of mental activity. It likes to explode. The mind's role is to place it on steady pace, and generate power that actually changed things, instead of just exploding on spot.
