No one is taking your right to write whatever your like in your blog.
Also, no one is taking your right to self-perpetuated, mindless self-slavery.

It, also does not mean that others have no right to criticize your actions.
We all have to take consequences of our actions.

Your reply has a lot of logical fallacies. No one is asking you to be rocket scientist, activist or famous artist etc.
I am not a talented person myself. Neither am I a scientist or innovator etc.
You don't have to be any of these to be able to share valuable information.
There are many interesting and valuable topics related to improvement of our society, culture or natural environment etc.
I am certain that you have encountered any of these within your life, which are worth sharing. Even if someone else already shared it, it is still good thing to re-share it. The more we share such knowledge with others, the better. Activism is not just about having talents you can express, it is also about sharing what is important.
The question is if you want to contribute something or, you just prefer to revolve your life about bullshit (and yes I love the word "bullshit" :P ).

And regarding your self objectifying selfies of your buttocks, I find it very disappointing to every person fighting for women's rights in our society. For all people trying to stop objectification of women. The worst kind of objectification is when someone perpetuates it by performing it on themselves by mindlessly following unsustainable social behavior within culture.
Like Johann Wolfgang von Goethe wisely said once:
"None are more hopelessly enslaved than those who falsely believe they are free."

And what I am talking about has nothing to do with personal right to nudity. I think that nudity it is basic human. Everyone should be allowed to walk around naked if they choose.
What is important is the reason why people walk naked, not an act itself.

People should not be rewarded for something, they have been lucky to be born with such as body or face features, race, nationality, gender etc.
People should be rewarded for their positive social achievements
Rewarding people for such thing is an utter disgrace to all humanity.
