I have no doubt that they have opinions about Vatican II and Pope Francis.
You are a recent convert. I have been dealing with such people that hold such opinions since the 1970s. I could tell you things that would curl your hair. I shall not, however.
If it is any consolation, it was the same ilk of people who used to say the most dreadful things against the now canonised Pope Saint John XXIII and Pope Saint John Paul II as well as the now beatified Blessed Pope Paul VI. They are sad people indeed, those who would oppose the very saints of God.
I would suggest you read the documents of the Council in order to understand why the Catholic bishops of the world, gathered in ecumenical council, decreed the urgent need for reform and renewal.
You could begin with the constitution on the liturgy,
Sacrosanctum Concilium.

Personally, in so far as I can, I try to limit my exposure to people who say problematic things – which is easier now that I am in retirement. Those who hold outlandish opinion do not get to have access to me or they are summarily banished from my presence…other priests, not retired, now get to deal with them as I once had to.
Perhaps you should consider thoughtfully whether interacting with these people are an asset or a liability to you. On the other hand, what you have already seen does at least show you clearly the very attitude that Pope Francis spoke about.
