No, be as unfriendly towards Britain as you want, but taking that out on people abroad who happen to be British is way out of line. I said this elsewhere, but we're not in the Middle Ages; the tribe doesn't get to own the individual in the 21st century. The British people affected by these policies (again effectively only implemented by Sweden in the whole EU) are overwhelmingly likely not to be the people who decided to slap everyone in Europe in the face. Taking this idea to its absurd conclusion, European countries should've deported refugees from Nazi Germany because the Nazis were making trouble for everyone. After all, it's okay to be "unfriendly" to people who are from countries that did bad things to you (setting aside the absurdity of describing uprooting a woman nearly in her 80s from her home of 21 years as just "unfriendly"). The trend today is to be trigger-happy with deportation as if it's a nothingburger punishment like community service, but it has very real and very significant consequences to the people being deported and is definitely not something to be done out of spite.
