It’s okay if you do not like to talk about social issues on social media all the time uselessly i.e. just whining and complaining about what’s going wrong and still being unable to do anything about how it can be corrected; also, it’s okay to do it. There is no thumb rule as to what you have to talk about and what not. You may be a chatterbox on social media and still like to stay alone without talking to anyone in real, or quiet and unrevealing on social media yet a very open-minded and open-hearted person in real. You may be deconstructing and strategizing, thinking about public issues minutely in your mind, yet not revealing a thing to anyone, or you may just be sharing what’s already given everywhere yet not going anywhere with it.
Just do what you feel like doing, you have been given right to freedom of speech and expression for a reason and nobody shall stop you directly or indirectly from using it.
ONLY THOSE WHO ARE AFRAID OF YOUR VOICE TRY TO SHUN IT.
