I do not understand why people have a problem with this. Paul tells us: "many are sick and weak among you" (1Cor11:30) Yet people continue to lie and tell each other they can eat whatever they want with no consequences. I can assure you that if you were to talk to Paul he would call you on this. The problem is the example we are setting for others: "Whosoever therefore shall break one of these least commandments, and shall teach men so, he shall be called the least in the kingdom of heaven" We can do what we want but we have to be careful what we teach and the example we set. God is going to hold us accountable for that. (Matthew 5:19) Even sinners are justified before God if the are humble and admit their guilt. "I tell you, this sinner, not the Pharisee, returned home justified before God" (Luke 18:14) The word MANY is a word we need to pay attention to.
People have a problem with this because it's not commanded in the Bible to Gentile believers, and personal convictions shouldn't be presented as God's commandment. It's not like anyone is against you, or your conviction specifically.
Apostle Paul was very careful not to do this, emphasizing if something was his personal judgments and differing them from God's words.
I believe that if this practice was of consequence to uphold, it would have been commanded to us in the New Testament, just like meat sacrificed to idols and blood was advised multiple times to abstain from.
If someone is Jewish, I would not interfere with their convictions either. Messianic Jews
might be led to observe certain things that us Gentile believers don't have laid upon us, or not, I do not know... that's between them and God to figure out... but as for the Gentiles:
Acts 21:25 As touching the Gentiles which believe, we have written
and concluded that they observe
no such thing, save only that they keep themselves from
things offered to idols, and
from blood, and from
strangled, and from fornication.
