Every person IS different and unique and every match is different, but of course we all have things in common or nobody would be compatible. Our uniqueness is what creates balance in the world, if we all had the same talents and interests the world would be a very boring and unbalanced place.
Of course singles are very capable of getting in their own way too, everybody makes bad decisions sometimes that have a negative impact and that includes singles. But if the community truly wants to be helpful then they have a responsibility to look for solutions that are helpful and sensible, not ones that make the problem worse or are hurtful. This is not singles vs. the community, singles are a part of the community, we should all be working in harmony not in a combative way. If the singles are saying certain things harm rather than help, believe them, they live it and are asking you to listen with an open heart and not with judgement.
