why is there a "britney vs. stripped" poll?

don't people know by now that xtina wanted to copy pink's missundaztood with stripped? i mean, there
is an interview with linda where she says that xtina came up to her and said: "i want you to write my missundaztood"...

is it eligible to have a poll like that then? (especially when people claim that brit tried to copy xtina ever since lady marmalade... huh? what? huh?)
this place can be sooo strange.
