m(._.)m

就是说和他说话多了，你会就顺着他的思维想问题，差不多此时的智商就差不多了，实际上这个有点贬低他人的意味

the meaning of this sentence is: because he once made your IQ at his level.
拉到。literally means "drag". in this case, it probably means that his level is lower than yours.
(did i make that clear? i'm new here, i would like to add friends with you.)

有一句话是：
我从来不会和一个傻瓜争论
因为他会把你的智商拉到和他一个水平
然后再用他丰富的经验把你打败
”拉“ can be either concrete or abstract.
Here, it means " make".
make it at the same level.
我们也可以说 ”他把班级的平均分数拉低了“。
希望可以帮到你。

“拉到”有使水平下降的意思，This sentence means that what he had been so stupid that his behavior even affected your behavior greatly, so you did things wrong because you are no more clever than him. wish I can help you.

means “decrease to”
使....下降

It is said: Never argue with an idiot. He will drag you to his level and beat you with experience. I think 拉到 here just like drag to

用来骂人的话，但是用语比较文明。这种习惯用语具体很难说清楚，用“拉”这词的话更有画面感更加形象生动。

この言葉の意味は、「彼はバカです。彼と一緒に時あなたのIQも彼によって低下しました」。その中に、他の人を貶めることの意味があります。でも、もし喋る人と喋られる人は親密な友達なら、これはただ単純な冗談です。
ここに、「拉下」の意味は、低下させることです。
私の日本語はあまり上手ではなく、hope you can understand me.

拉就是改变物体的位置，包括抽象的和具象的。智商就是抽象的。
