1) If a man is attracted to women with thin arms, it is his responsibility to seek out women whose profile pics show their thin arms. Not to take a risk with Emma wearing attire that covers them, going on a couple dates where she covers her arms (while at the same time complimenting her otherwise beautiful figure), then upon seeing her uncovered not so thin arms, giving her a look of shock and disgust and ending the date early (or worse, calling her a liar and telling her she has fat arms to her face). Emma did nothing wrong in wearing flattering clothing in her pics that emphasize her beautiful face/figure/legs while covering the arms she feels are not her best asset.
2) IMHO (and this is just my opinion, please no flames or hurled tomatoes), a man who is uncomfortable dating a woman from Latin America who is of Spanish or Portuguese ancestry (for whatever reason) will probably not be tremendously happy with an Italian woman either, regardless of where she moved to his city from, due to cultural similarities. But if a man does not want a woman from a Latin culture, he needs to not only look for "White/Caucasian/European" under ethnicity, but also stick to women whose pictures clearly show they are of Northern European or Eastern European ancestry (and if possible, that give other clues to this on their profile), rather than taking a chance with a woman that looks more Mediterranean- then calling her a hothead once he hears her Spanish accent. So whether Claudia truly just identifies as more "White/Caucasian/European" than "Hispanic/Latina", or she is simply avoiding idiots who make interesting assumptions about her temperament and call her names about it, she is not committing deceit.
3) If a man wants a woman who has previous relationship experience, he should probably look for women who are divorced, widowed, or whose longest relationship was over a year long. Not take a gamble with one that stated "less than a year"/"between 6 months and a year" (whatever is available on the site) hoping that it was 11 months long- then several (otherwise fantastic) dates down the road finding out that Suzanne had only dated someone casually for around 6 months before him, assume that there is something pathologically wrong with Suzanne, and dumping her.
