Yes, some say that it is silly and ridiculous for Catholics to determine, despite being nothing more than laity, however devout, that they have the authority to decide who is and who is not a member of the church.  Perhaps those who do these things should try reading the catechism more, or consult with the God Ordained Clergy, who alone have the power to eject people from the Church, and hence condemn them, rightly, to eternal torment in the pits of Hell.  I do hope this comment is well received and provides some guidance and insight where it is so evidently needed.
