I am tired of people assuming I am a muslim because of my ethnicity

I know this will sound weird or maybe even racist to some extent but I swear I am not and I apologise if it feels that way ahead of time.
I am a Turkish-Greek who was born in UK and raised mostly in Turkey for majority of my life, as a result I have a Turkish first and last name (both are of Latin origin, so it's not a traditional muslim name). I want to mention that I am also not a muslim, and Turkey is a secular country, so I grew up with such beliefs. I have came back to UK during Sixth-Form to study, and for the longest time I can remember, whenever I would tell someone I am not a muslim, they would look at me in a shocked way, almost as if I broke their whole expectation of me. I quite literally have eaten a BLT sandwich around such people on multiple occasions too, so I don't know what's up with that.
Another thing is that, girls who I have basically never talked to or had minimal interaction with would ask me out or show romantic interest towards me. They often happened to be muslims, who would also often be shocked when I tell them I am not a muslim.
When I was having an interview for a university, despite on my UCAS form declaring that I am not a muslim, and marking my religion as agnostic, the interviewer kept talking about the turkish muslim students at the uni and assumed I was muslim too until I had to mention I am not one.
I swear I have nothing against islam or anything like that, however this has been happening for years and ONLY in the UK. I have lived in other countries and nobody assumes someone's religion because of the country they are from (despite the fact that country is obviously secular). I feel like I am just some sort of a diversity raising tool for these people. I may sound frustrated because I kind of am. Nobody assumes a Japanese person's religion but for some reason I am assumed to be a muslim by default? Can anyone tell me if they had similar experiences like this or if I am just crashing out over nothing?

you are valid, and don't listen to others who may call this islamophobic.

I don’t see how this could be flagged as islamophobic in any way. I am Muslim and unlike you, OP, I could not pass off as a “stereotypical” (or at least how many prople expect all mulisms to look like) if I didn’t wear the hijab. I immagine that for men especially who happen to be arab or look arab this can be a stuggle with people assuming your religion based on the way you look.
I always feel is important to remind people not to judge a book by it’s cover. In this case not all muslims are arab and not all arabs are muslim.
Your situation sure sounds tricky and I don’t know what kind of advice to give you.
I find what happened to you during your interview quite peculiar, because I don’t understand why they felt the need to being that up, is your religion important for the porpose of goving you an offer or not? That’s something that genuinly left me confused

I can see that being frustrating people make an assumption based on appearance and background. It's racist to assume that you're muslim because of your ethnicity. I think you are perfectly valid.

I don't see how is it RACIST to assume someone is a certain religion.

it can be because there are some people (keyword some) that take any statements like this as an attack towards islam. i am just trying to boost the op’s feelings here.
it inherently is stereotypical, to assume someone’s race/religion/gender/ethnicity by their skin colour and appearance, which is what has happened to op.

how can you assume someone's... gender, by their skin colour?

I personally wouldn't go as far as calling it racist, I am sure the vast majority of people who make that assumption don't to it with malicious intent, they probably assume that because the vast majority of people they met that look like him, happen to also be Muslim.
I am not saying is right, but I don't think this is racist
