Fair enough
There is a very large amount of studies that show that people like people that are like them.
The link you provide shows a coefficient of .47 for actual similarity, and .39 for perceived similarity. I'm not good at statistics, but that seems like a far cry from "the reason why people like other people is that they are like them." which is the line I was replying to. If I'm understanding it correctly it would be more accurate to say "people are somewhat more likely to like someone who is like them." If that's what was originally written, then I probably wouldn't have replied.
r, or Pearson's Correlation Coefficient [1], is a value from -1 to 1. for r < 0, the variables are negatively correlated, for r > 0 the variables are positively correlated, and for |r| ~= 0, the variables are uncorrelated. 0.47 and 0.39 are high values of correlation.

Yes, you are an outlier. There is a very large amount of studies that show that people like people that are like them.
