I'm clearly wrong, but here goes...
I got there by reverse engineering. Why didn't they mention quality and aesthetics? The only thing they objected to was the character's age. They have something against lolis. The reasons for objecting have been limited to character bias and moral qualms. In conclusion, the one who objected may have been objecting on the grounds that lolicon and pedophilia are immoral.
If the OP thought that they meant that, then he probably meant people who have no moral qualms with the issue when he said 'people who don't give a shit'.
