Half of the population still thinks that homosexuality is wrong. US and Europe are more already more liberal than the rest of the world, which homosexuality is still a taboo over there. In certain middle eastern countries, so much as showing some skin is considered unlawful and punishable. The people in these countries believe it as moral standards and anything else is wrong. Weed is prohibited in certain countries and it is considered wrong but not other countries. Until certain time in US, homosexuality is punishable by law, the reason it exist is because back then people feel that it is wrong, homosexuality is still punishable in certain countries even till today. So which moral code should we use as what is right and wrong?There is just no way to have a standardisation and everybody adhere to their own moral ethics by faith, their personal standards or by law.
.You miss the parts where I said the costume change isn't keeping me away. I'm still collecting. Though honestly the stories are IMO not interesting and I may drop soon if they don't fix. To throw your argument back at you... What's wrong with keeping him the way he is? He's always been like that, and the fans who have supported him for years prefer him that way. The fact that they think they have to make silly changes like that is what bothers me, because as you say the fans that stay are the ones not interested in superficial changes. That implies that they are trying to cater to the fans that aren't going to be sticking around anyway, or are fickle enough as to only read Superman now because he doesn't have trunks anymore
With regards to your question, I would say that there is nothing wrong with the way he was because it is only superficial changes like his costumes, it would be fine if they had kept his costume, nothing would have changed. But Superman is overdued for a reboot due to the convoluted history. A fresh start showing him less powered up and more of social justice would be a great start for a reboot to re introduce his origins. DC could have done all that and still kept his costume and nothing would have changed. The only difference now is he is wearing a different suit, it is not silly because it reflects an era we live in. Sure this is a way of getting new fans because older fans are getting old and they will not be here forever. If some superficial changes and modern stories can bring in new fans that will grow to love Superman, I say why not.
Take the new film for instance, it seems like the film will embrace Superman and give us someone that believes in the truth, justice and the american way. The difference is it would be set in a world where we live in, where aliens do not exist and any aliens would be viewed as hostile. This is a story that will related to the general audience, people will believe a story like this would exist. So yes, this is DC and WB's way of getting in a new generation of fans but yet at the same time, they're still retaining the essence of Kal el. How this could be seen as silly, I do not know. Because if DC is unwilling to budge and to evolve, their fans would only get older and there will be nothing left after this generations. Ultimately sales is important to them, if nobody is buying books, merchandise and watching movies on Superman, then there is no point investing in this character.
