Your sentiment is understandable. I am sure Catholics are not unique in the failure of compassion to which you refer. But we should know better and God will surely hold us especially culpable.
Thank you for understanding.
Catholics are
absolutely not unique in this regard; on the contrary, most real-life Catholics I know and have met are compassionate, understanding and loving. In my daily life, I fear certain groups of Protestants, not to speak of irreligious people who are also bigots (who generally happen to be the physically violent ones), more. I find “Internet Catholicism” quite different from real Catholicism - something that can not be dismissed by saying offline Catholics are liberals; I live in a very conservative diocese.
And I agree, we should know better, and God will hold us especially culpable. That goes for me too; I was autophobic in my past, and may have said bad and hurtful things about trans people. I repent for that regularly. At least my gut reaction was to avoid the subject, rather than lash out; I only lashed out if people forced the subject. But that is still no excuse. I probably sin against charity on other areas, too; we all do. But still, nothing makes me more angry than sin against charity, and it is the one sin I feel obliged to speak (harshly) out against, since that was really one of the few sins which brought Our Lord on a tangent, too. In addition to the temple profit thing.
Interestingly, Our Lord could possibly be seen as uncharitable toward the Pharisees - after all, they were often sincere (as evidenced by multiple events in the Gospels!), and wanted the best for their people. But they cared more about society than individuals. I think that is something we all do, from time to time. But we shouldn't, and I think it is a particularly tempting sin, now that society is changing faster than most of us (including me) would like. I'm not saying we shouldn't care about society, but our first and most important calling is to bring sinners to Christ. We can't do that if the world sees us as uncharitable and anti-compassionate. And that is, sadly, an all to common and very mistaken belief these days, in part caused by anti-catholic propaganda, but sadly, in part caused by Catholics. It saddens me.
