How Are Fundamentalists Just Like the Judaizers of Paul's Day

The Judaizers of the Apostle Paul's day were Christians who taught that Gentiles have to become Jews as part of being "saved".
Which includes obeying all of what's written in the Law of  Moses -- the first 5 books of the Bible.
 
These Judaizers opposed Paul, hating him for he taught that Gentiles can be saved without becoming Jews.
Not only that, we don't need to observe all of the Torah  --  the Law of Moses.
The Judaizers saw themselves as the true Christians while this Paul, he was just a semi-Christian because he accepted only part of the Law, in their opinion.
 
Paul saw them as enemies of the Cross of Christ,
going so far as to declare them "accursed" for their opposition to his gospel(Galatians 1.6-9).
 
How are today"s Fundamentalist "Christians" the latter day incarnation or spiritual descendants of the Judaizers of the first century ??  
Well I'm not saying they claim that Gentiles have to become Jews.
They don't.
But they do one thing that Judaizers used to do.
Namely, "make it hard for Gentiles to come to God"(Acts 15.19).
How, by observing and accepting parts of the Law of Moses that are a stumbling block to nonbelievers.
Example, the Law, in terms of the book of Genesis, claims that people in the distant past lived to be 300, 400, even 969 years old (Genesis 5.27).
Now THAT is what I call a real stumbling block to people in the 21st century.
And Paul the Apostle specifically is critical of such passages in the  Law of Moses.
For he says don't have disputes about "endless geneologies"(1st Timothy 1.4; Titus 3.9), meaning geneologies of men living "endless" lives,
which is what 969 years amounts to:
14 times the lifespan of today.
That sounds pretty "endless" to me.

When these Judaizers of today preach Genesis 5.27 as truth, they are going directly against Paul's gospel --  
If we take 1st Timothy 1.4; Titus 3.9 as part of Paul's gospel.
And therefor the curse of Paul falls upon them --  and if Paul's curse was in line with the Will of God, the curse of God is what falls upon them !!!
 
Paul counseled, Don't let your conduct be evil spoken of.
Well that is directly what YECers -- Young Earth Creationists  --  are doing every day.
Every day nonbelievers see YECers (like Ken Ham) talking 6,000 years (10,000 max) as the age of the universe.
That is enuff to fill the hearts of science enthusiasts with contempt.
(Contempt for who?? For Christ !!!)
So the YECers are thoughtlessly driving people into the arms of Satan by their conduct.
But that's not the worst part.
The worst part is that these YECers/Judaizers don't care.
They're oblivious.
I've heard that the mark of a sociopath, which is what mass murderers tend to be, is a lack of empathy.
Well, it seems to me that YECers are something like that.
They have no empathy  -- no feeling  -- for what they are doing to people for whom Christ died.
