You have ceded too much territory to the homosexualists by accepting their confounding of the temptation ('orientation') with the sin ('practice').
The problem lies with the ordination of those who call evil 'good' and good 'evil', or who yield to grevious temptations, not with the ordination of those subject to any particular besetting temptation.
I have little doubt that for centuries, the Latin church (and for that matter the Orthodox church) has ordained men who suffer from temptations to all manner of sins from theft to sodomy, from wrath (which Our Lord equated with murder) to fornication. The problem besetting the Latin church arose when the gate-keeping at the seminaries, in terms of judging the stability of candidates for ordination, was passed to secular psychologists from those with traditional moral and religious sensibilities (who had typically discerned well which men were fitted for celibacy).
Well said.
