One striving to keep the Jewish commandments should indeed be concerned about this commandment. The target audience of the article is however not the Jews but rather Christians.
Jesus Christ discussed all the commandments of the Jewish Law with His disciples. These conversations are recorded in the Holy Gospels and explained further in the Epistles. Jesus taught to not use the commandments blindly but look into the meaning of them. The Christians were supposed to have a higher order of righteousness than the Pharisees, as you may have read, if you ever do such a thing.
Neither Jesus or His apostles never mention veneration of icons negatively. Positively, they do: it can be seen from Galatians 3:1 that crucifixes were a part of their worship; and here St. Paul expressly tells us that by contemplating the Holy Images (Icons, in the language of the original), we are to become holy ourselves:
we all beholding the glory of the Lord with open face, are transformed into the same image from glory to glory, as by the Spirit of the Lord. (2 Cor 3:18)
Nor is it the only example where something doctrinally established by the Jewish Law is rejected by the Christian Church. As you probably know, the eating of pork is prohibited by the Jewish God-given law. Nevertheless, among the first acts of the Christian Catholic Church was to lift the restriction.
The veneration of images was made controversial around 7-8c and this heresy was anathemized by another Church council. You may or may not know that Triumph of Orthodoxy celebrated that very event in the Orthodox Church not long ago.
If anyone presuming to advise us really wants to hold a civil discussion about how to worship God, let him begin by visiting a Catholic Mass or an Orthodox Liturgy. We have worship cervices every day in a church near every one of you. Attend and learn; observe proper worship and proper veneration; stay for coffee and talk to the faithful and learn from them; till such time, I suggest very civilly to all of the Protestants, mind your own business: this is a 2000 year old Church founded by Christ that does not need a Protestant advice.
