I find it more weird that you're immediately doubting the data because it goes against pre conceived notions.
Also from the website itself the definition is: "The FBI Uniform Crime Reporting Program defines hate crime as a committed criminal offense which is motivated, in whole or in part, by the offender’s bias(es) against a race, religion, disability, sexual orientation, ethnicity, gender, or gender identity."
Looking at the data again personally I find it interesting that there was no anti white crime reported in CA but it was the third most reported hate crime in Texas
