I have heard stories of people who mixed with gypsies, and ended up stuck in situations where they were the means by which others could wash their hands of various crimes.
Taking the girl I like as an example. That time she really tried her best to entertain the little gypsy child (she was really a gypsy, not something that looked like a gypsy). You should have seen her, she seemed to be the embodiment of all that is goodness, compassion, sweetness, etc. And all these really beautiful things about her were dedicated to a gypsy.
The gypsy's family (other gypsies) didn't appreciate it at all. They didn't even bother to thank her for what the girl had done (give her best to make someone happy), when it got late, they just took their daughter back as if nothing had happened. A Gentile would at least have been grateful for the fact that this girl dedicated her whole evening of celebration (were celebrating a wedding) and vacation from work to a daughter (and she works a lot, she even brought her work on her training holiday, she would have had every right to be happy that evening).
But the gypsy family looked at the girl I like as if she was the real monster incapable of positive feelings. This girl devoted all her ability to do good to people who couldn't even appreciate her kindness, indeed, who had no way of understanding her sweetness, indeed who in the end found an excuse to take back their daughter as if she had been "kidnapped".
Think about that when you decide to love a Jew, help a gypsy, sacrifice your life for stupid ideals like "even Communists have the right to express their opinion" or "if a cardinal abuses minors in a penthouse or an Islamic dictator makes a law to castrate women, it is religious freedom and that's fine". People should really understand how to choose their battles. Otherwise they will find themselves throwing their lives away.
