Unfortunately, you, and many others, have managed to pick out and emphasize the negative in the most powerful, beautiful and poignant section of what the Pope wrote.
A better translation of that section appears below with emphasis on the words of healing:
Certainly, for some time now, and once again on this specific occasion, we have heard from some representatives of that community many unpleasant things – arrogance and presumptuousness, an obsession with one-sided positions, etc. Yet to tell the truth, I must add that I have also received a number of touching testimonials of gratitude which clearly showed an openness of heart. But should not the great Church also allow herself to be generous in the knowledge of her great breadth, in the knowledge of the promise made to her? Should not we, as good educators, also be capable of overlooking various faults and making every effort to open up broader vistas? And should we not admit that some unpleasant things have also emerged in Church circles? At times one gets the impression that our society needs to have at least one group to which no tolerance may be shown; which one can easily attack and hate. And should someone dare to approach them – in this case the Pope – he too loses any right to tolerance; he too can be treated hatefully, without misgiving or restraint.
Instead of seeing the true weight of the merciful heart of what is written (emphasized above) people have pointed at the last sentence of that section, wrestling it entirely out of context and distorting the message.
