When confronted with lack of commitment or shaming you for being single and happy, their own arguments work wonderfully against them. You don't need agree and amplify, just straight as they say them.

• Women don't need men (Women need men like a fish needs a bicycle)
• I know enough to know that no woman should ever marry a man who hated his mother
• I am "bitter and angry against women", sorry
• I'm immature
• I'm a boy, not a real man yet
• I'm right wing [I'm not]
• I can't get laid [of course I can]
• I'm a quitter [not anymore with so much time for myself]
• I don't make much money [easy to fake when you are a minimalist]
• I might be gay [fat chance]
