Why do so many anti-British trolls pretend in their profiles that they are British?

@Bootsiebaby Yeah I understand! I was laughing " who do they think they fooling"? Didn't mean to offend you

@Bootsiebaby on this post under your question in your comment section

@Bootsiebaby .."who do they think they are fooling"

@Bootsiebaby I see what you mean. I mistyped "there" for "they" and it's corrected
So I am the fool. Cool
Why are you being so defensive? As I said I didn't mean to offend you let it go

@Bootsiebaby Ah ok. I didnt mean to freak you out. My apology and definitely not British nor a troll to pretend to be British.

@Bootsiebaby Thank you:)
