Despite what people want to believe, it is absolutely difficult being the only person of colour (POC) in an academic environment. When you're the only black person in an entire room of only white people (yes, I go to a Russell Group university and yes, I'm the only POC on a course with more than 200 people), you begin to feel incredibly uncomfortable. I have had people on my course ask me if English is my first language (despite being born here and speaking perfect English) and tell me that they'd never step foot in the area I'm from. Whilst I didn't find that offensive, you quickly realise that you have NOTHING in common with the majority of the people there and that socialisation becomes an unnerving experience. It's even worse when lecturers and tutors expect less of you because you're a POC. So yes, I absolutely wish that there was more POC in my course and at my university. Yes, I would RECOMMEND you find a university where you feel comfortable with the diversity, because if you're worrying about it now, then it may genuinely impact your studies when you're at university. As for the people criticising you, with all due respect, if you're white you can never begin to understand what it is like to be in an academic environment where you're uncomfortable, alone and thought of as less (often subliminal so I'm not accusing people of being racist).
