What are my reasons? Ok I have quite a few so here we go.
1 Americianing animes and unneeded edits (meaning sucking all of the culture out of the anime and replacing it with american culture)
Seriously while I know you need to edit out bad words and unsuitable scenes, changing a rice ball into a sandwich, or calling it a Donuts was a very bad edit that wasn't breaking any rules and could have been left alone. I mean seriously does it harm you in any way to let the culture stay in the anime without gutting it, and filling it with your own? I think now yet these idiots went and did it anyways.
Another example of this is completely removing lines from a character that aren't offensive but go with the character skills or style. This happen in Hoshi no Kirby (Kirby right back at ya) with Fighter Kirby and mirror Kirby's copy abilites since in the original he would say the his attacks he could call them out but in the 4kids dub they edited this out.
Another would be the removing of weapons and replacing weapons with other items. Seriously I have watched american cartoons where the characters smoke and have guns. Elmer Fudd and Yosamie Sam are two good examples of this and the censors let this fly, yet they removed the characters weapons and replaced cigarettes with lolipops when they not only show this in american cartoons, but actually see people in america smoke in real life? (Insert face palm here)
2 The unneeded changing of names unless they were unsuitable.
Seriously what was wrong with their original names that you needed to change them? Because American names are easy to remember and are more marketable? I call bullshit on this one! While I can remember one anime actually changing a characters name because it was unsuitable (The name is picodevimon since Pico mean Penis in another language and some could say he is penisdevimon) 4kids changes perfectly good names that were not offensive and some of them we have in our culture one of which being Honda (Tristan in the english version of Yugioh)
3 You care so much about making a buck that you will do anything to post an anime in america even if it means butchering it and sending it to the unexpected views.
Serious this one is the biggest one. Many kids animes from Japan are the equal to teens and young adults in our country yet they will still accept the anime anyways and destroy it just for a quick buck. One good example of this is one piece. One piece from what I saw of the original is a very violent anime that should have been sold to another company that would do the anime justice however these retards decided to go ahead and dub it anyways gutting everything that made the anime watchable and edited so much that it left plot holes you had no clue about unless you watched the original Seriously if you were to watch the original and then the 4kids dub you would think you were watching two different things and it was done only to make money without caring about their viewers.
There is more but I will stop for now.
