If you are a Gentile you should know that most of the prohibitions of the Bible apply only to Jews and not to Gentiles. Gentiles are obligated to fulfill only those few commandments that the Creator gave to the descendants of Noah (see Genesis chapter 9 and then ask an orthodox rabbi for details).
It is sinful however to deny that Jews are obligated to fulfill the sometimes difficult commandments of the Bible, such as,
"You may do work during the six weekdays, but Saturday must be kept holy as Sabbath of Sabbaths to G-d. Whoever does any work on [that day] shall be put to death.
Do not ignite any fire on the Sabbath, no matter where
[R. Aryeh Kaplan's translation of Exodus chapter 35 verses 2 and 3 ]
(Nor can one claim that the time limit for the Sabbath commandment has expired in light of Exodus 31:16, ''The Israelites shall thus keep the Sabbath, making it a day of rest for all generations, as an eternal covenant''.)
Please note: It is not the responsibility of the Gentiles to punish Jews who turn on car engines or perform other forms of work on Saturday. And here, is certainly not the forum to discuss under what conditions do Jews have the moral duty to execute Jews who are not Sabbath observers.
My advice to the Gentile that wishes to be a really righteous person, is to influence Jews to observe all the laws incumbent upon them.
And this idea is reflected in the Biblical verses of Deuteronomy chapter 29 verses 23 and 24.
"And all the gentiles shall say, Why did G-d do this to the land?
What was the reason for this great display of anger?
And they shall say, It is because they abandoned the covenant that G-d, the L-rd of their fathers, made with them when he brought them out of Egypt."
In the book of Genesis, after the Bible records that Cain murdered his brother Abel (Hevel), the L-rd, then speaks to Cain and says,
"What have you done?
The voice of your brother's blood cries out to me from the ground."
According to Rashi's analysis of the text, the L-rd was telling Cain that not only would he be held guilty for Abel's murder, he would also be held guilty for having shed the blood of all the future generations that would have been born from Abel and his wife.
The Chafetz Chaim commented that if a man can be punished for the effects of his actions on future generations, how much more so will he be rewarded for spiritually saving someone.
When the newly religious man raises other generations in a religious lifestyle, the credit for the entire family's good deeds is attributed to the original teacher.
And even though until now, I have written in praise of striving to make the secular repent, for the sake of honesty, I must admit that sometimes the spiritual damage caused by contacting the wicked (to make them repent) can be worse than the benefits.
Those that wish to fulfill the words of Deuteronomy chapter 29 verses 23 and 24 in a safe way, might be interested in spreading by means of the internet, articles that lead to repentance.

demands from the Gentiles.
