I can translate this to Simplified Chinese, but I should note this contains strong language and personal attacks.

Here's a direct translation:

如果你一边抱怨本·阿姆斯特朗出轨并经常说他的坏话，一边又投票支持风流成性的唐纳德·特朗普担任总统，那么说你是个该死的傻瓜可以吗？

However, I'd point out that regardless of language, this type of statement combines:
- Strong profanity
- Personal insults
- A logical argument about perceived hypocrisy

Whether it's "ok" to say depends on context, audience, and your goals. If you're trying to persuade someone, this approach typically backfires. If you're venting frustration among friends who accept that language, context matters differently.

Is there something specific you'd like help expressing more effectively?
