I am a very spiritual/religious person. From what I believe (Hebrew scriptures), it helps me to know that God looks at the heart, not on the outward appearances. And so I believe that people who judge on the outward appearance instead of the heart, are people who are not close to God and thus are not to be listened to.
These are scriptures that come to mind:
1 Samuel 16:7
וַיֹּ֨אמֶר יְהוָ֜ה אֶל־שְׁמוּאֵ֗ל אַל־תַּבֵּ֧ט אֶל־מַרְאֵ֛הוּ וְאֶל־גְּבֹ֥הַּ קוֹמָת֖וֹ כִּ֣י מְאַסְתִּ֑יהוּ כִּ֣י ׀ לֹ֗א אֲשֶׁ֤ר יִרְאֶה֙ הָאָדָ֔ם כִּ֤י הָֽאָדָם֙ יִרְאֶ֣ה לַעֵינַ֔יִם וַיהוָ֖ה יִרְאֶ֥ה לַלֵּבָֽב׃
But the ETERNAL said to Samuel, “Pay no attention to his appearance or his stature, for I have rejected him. For not as man sees [does the ETERNAL see]; man sees only what is visible, but the ETERNAL sees into the heart.”
---This is about finding the right man to be king, and when Samuel thought he had found the one who outwardly looked like he should be king.
2 Samuel 14:25
וּכְאַבְשָׁל֗וֹם לֹא־הָיָ֧ה אִישׁ־יָפֶ֛ה בְּכָל־יִשְׂרָאֵ֖ל לְהַלֵּ֣ל מְאֹ֑ד מִכַּ֤ף רַגְלוֹ֙ וְעַ֣ד קָדְקֳד֔וֹ לֹא־הָ֥יָה ב֖וֹ מֽוּם׃
No one in all Israel was so admired for his beauty as Absalom; from the sole of his foot to the crown of his head he was without blemish.
---This is describing a deadlocked man. He had to start cutting his hair once per year because his locks started to weigh up to 5 pounds. He was the most attractive man.
כָּל־יְמֵי֙ נֶ֣דֶר נִזְר֔וֹ תַּ֖עַר לֹא־יַעֲבֹ֣ר עַל־רֹאשׁ֑וֹ עַד־מְלֹ֨את הַיָּמִ֜ם אֲשֶׁר־יַזִּ֤יר לַיהוָה֙ קָדֹ֣שׁ יִהְיֶ֔ה גַּדֵּ֥ל פֶּ֖רַע שְׂעַ֥ר רֹאשֽׁוֹ׃
Throughout the term of his vow as nazirite, no razor shall touch his head; it shall remain consecrated until the completion of his term as nazirite of the ETERNAL, the hair of his head being left to grow untrimmed.
---Part of the sign of a nazyrite is not to cut your hair and is actually a part of being holy/concecrated to God.
So for me, people who are negative about it - it is a way of seeing into their heart...it is a good way to discern people to see how shallow they are etc. This is just what I believe. I am not saying you have to believe the same things. Hope it is encouraging though!
