It all depends how much effort you put in your work. I admit it did hurt me a bit, that comment about how drawing and visual arts take more time, and by extension more effort. And the underlying message that, by extension, they should be viewed as more valuable (okay, I think I am just being sensitive right now - I do admit a virtual hug wouldn't be unwelcome).
It might have to do with the fact that there is more commercial mass production in the case of literature and that often, visual artists do not have an organized commercial platform through which they can publish their work as easily. Comic publishers are so few and far between and the systems of Patreon, Tapas, etc. can fairly be viewed as viable ways to make a living off of art. I hope that this comment was the product of someone's discontent at the unfairness of it all (which I second and agree with absolutely).
Of course, if an author is in it just to produce anything, gain attention based on that anything (which can only be mediocre in comparison with what the author could achieve with great investment of time), then, yes, it would take more time. Writing about someone taking a dump requires 30 seconds. Making a half-assed drawing of someone on a toilet bowl takes 5 minutes.
However, what about Van Gogh who took around 1-2 days to make some of the most touching paintings in human history, reflections of his psychoses and suffering? Compared to Tolstoy who wrote "War and Peace", a masterpiece of literature, in six years. Is it that in this case, Tolstoy's work, a work about the baseness of human emotions on a background of his own despair, his own disillusionment, is more valuable because it took the author, the artist, longer to make than Van Gogh's paintings that were the product of a scared, broken, but beautiful mind that saw with different eyes and tried to just show the external world a pale reflection of his own perspective?!
I refuse to believe that. I refuse to compare genius and to monetize (in the sense of giving it a distinct, almost material, value) art, in whatever form it appears.
This being said, since here there is a question of collaboration, isn't it rather the selfishness and the lack of empathy of some people who solely write on this site that should be discussed? Is it fair to drag writing, literature as a greater ideal into this debate? Let us rather discuss about how some people who write on here do not understand the hardships visual artists face with finding the time to produce art, to make a living or gain remuneration from this art. How some people who write seem to be so imbued with their own ideas that they believe these ideas should be worshipped to the point of slavery.
Gosh, this is making me so sad, right now.
