Generalized rants about a group after bad experiences with a group should be allowed to provide a healthy outlet for an individual to eventually move on as opposed to suppressed and thus leading to more hatred and xenophobia festered inside.

It is healthier to be able to express how you feel so you can release the tension and frustration from the experience, eventually ground yourself and realize generalizations are not healthy and you shouldn't let your emotions lead you to a view of an entire group of people based on confirmation bias, and then continue to resume healthy interactions with said group rather than attracting more negative interactions because of a greater perceived hatred which can create a vicious cycle. This is a healthier attitude than pretending it never occurs because it is the societal expectation when many other people may have also noticed what you did. This creates more opportunity for open dialogue and can even encourage said group to be more cognizant and aware of the pattern in question and thus reduce its frequency. Often these things can just come down to cultural differences not being understood.

Specifically, I live in Canada, and there has been a noticeable increase in new comers from a particular country. From what I've read to try to understand what is occurring and approach the situation with understanding, in their country, people watching or staring at others is not considered rude behaviour and is perfectly socially acceptable. In Canada and probably most other countries, this is considered very rude and people are expected to mind their own business or at least make conversation if they are going to be looking at people, not just stare at them continuously out of curiosity or judgement or what have you. Now you can call me insecure and throw whatever label you want at me, but the fact of the matter is this does frustrate me, and I am merely human with flaws myself, and I know for a fact this is something that bothers other people too even if they aren't "allowed" to say it. Part of the frustration could be exacerbated by the fact that I am on the spectrum. And I make an effort to not be a hateful person but truth is, yes I have started to build some resentment towards new comers from this country because of this, even though this is not something I want to do. I plan to continue to work on this, but it would be made a lot easier if we had a culture that allowed discussions on common things from different cultures that frustrate us to help form a more unified, understanding, self aware, and accommodating melting pot.
