The fallacy of "The virtue of the oppressed"

[Dystopia]

Case by case. The rule would be, if you live in a place where you wont get arrested for dissent, or the worst you have to fear is a "fuck you" or "bullshit" or "that is not true", and no one is having you arrested and you are not being chased down by mobs, then you do not get to use being offended to claim oppression.

Having your claims or beliefs insulted or criticized is not a death sentence, it merely means you got offended.

It's not really that simple as you put it - The fact you are not arrested for holding a different opinion, religion and so on is not evidence that everything's cool... There's no oppression but you can still be "oppressed" (Read - Disadvantaged) trough prejudices.

The "fuck you" and "bullshit" is an oversimplification because it depends on the contexts.

Let me give you an example as I've already done with the topic of Islamophobia - Most atheists criticize Islam and Muslims because it is a harmful religion, and that is not dependent on race - However there are a group of people, particularly conservatives and nationalists, that don't like Muslims because they look "brown" in terms of ethnicity (regardless of your opinion on race, people from the middle east don't look the same as western white Europeans, it's noticeable). This means that there will be some discrimination, and sometimes it will not be only due to Islam

Here's what happened to me that's been troubling me:
I am an avid critique of Islam, I strongly bash Muslims, Allah, the quran, Sharia..... I don't blame them if they come to hate me for it. But I do it because it is a harmful religion. What happened is that my girlfriend picked my arguments and used them to be "racist" against Muslims by switching the phrase "I don't like Muslims(Islam" by "I don't like arabs" - In fact, you've probably heard someone saying they don't like arabs.. So how do we make a distinction between what is a worthy critique and something that already makes use of a bad prejudice?
