I think a lot of people are truly in denial about just how many illegal immigrants are in the country, and they all need housing.
What are you talking about? That is absolutely not what OP wrote.
> If I hadn't been hearing that the illegal immigrant population has remained unchanged at approximately 11 million for decades
The entire point is that OP is complaining about repeatedly hearing a falsehood. Hence:
> I think a lot of people are truly in denial about just how many illegal immigrants are in the country, and they all need housing.
There are far more than 11 million illegal immigrants in the US. When you take into account that as an objective matter of fact we are talking about far more than 3% of the population, your argument "no way 3% of the people are causing 30% of the price rise" becomes moot.
