Whether or not some action is discriminatory is inherent to that action. Something I do can't be considered discriminatory because of what someone else does. So for example, if I shake hands with all people of all colors, you cannot call that discriminatory just because my neighbor doesn't shake hands with people. That would be completely nonsensical.

Similarly, if the EU applies VAT to all goods sold, that can't be considered discriminatory just because some other country doesn't apply VAT.
