I believe what @Djordje was talking about, and I do agree, is that there are people who see the sex scandal as a new rhetorical talking point when arguing against the Catholic Church. This could be seen as disrespectful towards the victims.
Indeed, I know a person who is GLAD that the sex abuse scandal happened, because now he has a new talking point with which to debate Catholics with.
In this post: Several States Investigating the Catholic Church - #8 by PdotdQ I mentioned three ways for Catholics to respond. Unless we have a different understanding of what “Church” means, Catholics cannot leave the Church - it is the only one that we believe possess the fullness of truth and all the valid sacraments.
Again, I have talked about my view about this here: Several States Investigating the Catholic Church - #5 by PdotdQ. I don’t know what you mean by “rational”. As before, unless we have a different idea of what “Church” is, it is not logically coherent to leave the Church due to these scandals. My faith is not anchored to the charisma of the leaders of the Church.
