I get a lot of opposition for being a traditional catholic among my family and friends.
Although I am not sure I have ever stated it in these forums, part of what you are experiencing is a form of what is referred to as “tribalism”, which I mean by Merriam-Websters second definition: strong in-group loyalty.
And that loyalty is expressed in many externals.
When one is doing something which the “tribe” does not do, it tends to bring out some unpleasant reactions in some, and even stronger reactions in some, as one is expressing their “non-affiliation” with the tribe.
Pretty much the whole of those reactions are emotionally based, not intellectually based. And it makes it hard for those who do not “join the tribe” to get along with the majority; in some instances some of the smaller group are as emotionally rejecting of the larger “tribe” as those in the larger group do to the smaller group.
Some people are very formal in their lives; some are very casual, and some of each group scorns the other. It does not matter if it is about liturgy, or disciplinary laws, or any of a multitude of other aspects of how people live their lives. When the two collide, some will appreciate the “otherness” of the other group; some will either ignore the differences or pay no attention to them, some will react negatively.
And that is part of human nature.
In the 1950’s when my mother would go into Portland, the major city in Oregon to shop at the regional department store, she would dress up in her “Sunday best”, including a hat and gloves - as that was what proper society did then. The regional chain was bought out by Macy’s, and I have not seen a woman shopping in their Sunday best including hat and gloves in a bunch of decades. Anyone doing so would stand out like a sore thumb.
Would it be wrong? Of course not. Is wearing a mantilla wrong? Of course not - but the vast majority do not, so one is going to stand out like the sore thumb mentioned.
Is going to the EF wrong? Of course not, but the vast majority of parishes are not EF, and so one who chooses to attend is going to be noticed by those who attend the OF, and people being people, too many of them will react in a very tribal fashion.
Tribalism, along with racism is wrong, and it seems to be a part of the human fabric for many to engage in these reactions to others. And no one group is inherently right and the other wrong.
Which is another definition of sin - something which both sides are capable of committing.
Your choices are not wrong, but they run contrary to the choices of the majority. As long as you are not “using” those choices as in part a means of acting superior to the larger group, you are fine; but you likely will continue to find others reacting negatively as too many people react on emotion, rather than logic.
And if you use your choices in part to stand in judgement of the choices of the majority (and I am not suggesting you do in any way), then you are doing the same thing they are doing: reacting with emotion in a “tribal” way. It is hard to take criticism and not retaliate. Don’t go there.
