Not necessarily..every single single-guy I know, religious or otherwise, if he's invited to a wedding keeps an eye out just in case he finds a girl he likes, even if the set up at the wedding is for the most part separate. It's a good place to find one. How is that wrong? It's simply an avenue for him to find a wife. If a person is seriously looking to get married, he's allowed to look as per the hadeeth of Jaabir (ra) anyway.
I'd agree that it's an excellent place to find a partner, but not yourself, but your family. For example a guy's female relatives will be in female company and they can spot young girls who are suitable and they think would be nice for their son to marry. It's probably less so with men, since men aren't like women in that nature. My dad had 0 say and wanted 0 say in who his sons marry, not to say he doesn't care, but he feels it's a lady's job. One of my brother's wives was found in a family wedding 5 years ago, my mum saw her and during the wedding process ended up asking the girl's mum and 4 days later it was pretty much done and dusted.
