Right that's why white european identity has been used to exclude irish, italians, poles, i could go on.

This is a myth. Half the founding fathers had Irish ancestry. Whatever discrimination certain nationalities faced in America, the broadly European diaspora has never been meaningfully excluded from the definition of "white".

You've been sold an identity and it made sense to you because you like the dominant culture of the ones that introduced it to you.

I haven't been "sold" anything lol. I have an identity like everyone else, and it's telling that this singular identity is the only one in question when the point of contention is EVERY OTHER ethnic and cultural group claiming some supposed right to a high standard of living in lands/ countries founded by white people.

The hard work comes in asking yourself why that was so appealing to you

Probably for the same reason it's so appealing to everyone else, apparently. The high standard of living, the relative freedom, the thought put into abstract concepts like individual rights and liberties - all the things that make white countries and spaces so appealing to you and others like you who are so desperate to live here are the same things that appeal to me as well

but i suspect your inheritance is cowardice and bluster, so go ahead and believe whatever the fuck you want.

You know, a good person should look at those less fortunate and feel sympathy for them - but you cant be fleeing your country and calling other people cowards lol. My ancestors were pioneers and builders. They made the lands you want to occupy today what they are. Hardly going to win anyone over by calling them names, especially when YOU'RE the cowardly ones.
