Yeah. If anything the 'dating app' culture is a step back rather than an advancement. Unsafe sex often results in STD's which in turn leads to more strain on health services and a lot of unfortunate baggage not only for those who engaged in sex but their loved ones as well. I'd be ashamed of myself if I ended up catching an STD due to reckless behaviour.
If precautions are taken, on the other hand, then it's a different story. Yet judging by the typical profile on such sites I'm willing to bet that they often aren't.
