It’s ALWAYS a matter of selfishness when someone claims that nothing is lost if incense is not used.
Something is indeed lost.
There are a number of measures that can be taken by those that suffer allergies. The default in all cases need not be getting rid of incense.
I will give you a prime example. A great deal of incense is used in a fairly confined space in my Eastern Catholic parish, each and every Sunday. At least three folks (one an MD himself) suffer from emphysema. Rather than demand that no incense be used, they use medication to help them deal with the incense smoke. All take a tablet before Divine Liturgy. In one case you can actually smell one person’s inhaler, should he need to use it.
It’s nice to see them making an effort on their own rather than employing fake coughing and demands that no incense be used.
