religious art

there is a woden sculpture of a green frong being cruicified, with its green tongue sticking out and one of his hands holding an egg and the other holding a cup, which is currently being hated by the pope. a lot of people are trying to remove it from the art gallary as well because they say it's offensive to christianity which sees the cross as symbol of love etc.
indeed, most if not all artworks on religion that we come across are to do with beauty, mercy, greatness, love...... of god, these artists create such art possibly because they do not have words to describe their strong feelings about what they believe. if this is true, the lack of artworks such as those that depict nastiness of religion, or those that mock religion, suggests that people who criticise religion do not have as strong feelings towards religion (in an opposite way) as those who love their god.
interestingly, it is far from the truth that people do not have strong feelings towards religion in a negative way. so what do these people do when they want to express their repultion to religion? they certainly don't tend to do it through artworks such as painting, but they write, they argue.
so on one hand, people who say possitive things about god/religion do it through traditional artworks (including singing, painting etc); on the other, people who say negative things about god/religion tend to do it through text. I believe that this is not an accidental difference of expression, but rather it tells us what religions actually are.
in a blunt sentence, I would say that religions are pretty, nice, beautiful illogical bullshit that a lot of people have to depend on.
