Why are vegans so preachy/aggressive? Doesn't that hurt the cause?

The objection

“Vegans are so preachy and self-righteous it puts people off. They’re hurting their own cause.”

The answer

Partly true, and worth owning rather than deflecting. Some advocacy is genuinely counterproductive: shaming, smug, more interested in being right than being heard. If you’ve been lectured at and it put you off, that reaction is human. Granted in full.

Now look at what the objection actually argues. “You’re being preachy” is a claim about the speaker. It says nothing about whether the claim is correct. This is the ad hominem fallacy in its politest dress, and notice how conveniently it works: if the messenger’s tone is grounds to dismiss the message, you never have to examine the message at all. The annoyance becomes a permission slip not to think. Slave abolitionists were called shrill fanatics; the shrillness was real, and irrelevant.

It’s also worth asking why anyone gets loud about this. Nobody campaigns about your curtains. People raise their voices when they believe they are watching a serious injustice happen at enormous scale, right now, daily. You may think they’re mistaken (that’s a separate argument), but if the belief is true the passion is simply what consistency looks like. The strange spectacle would be someone who believed it and stayed politely quiet.

Both things hold at once: advocates should be kind, patient and strategic, and their occasional clumsiness is zero evidence about the facts.

So turn the lens around. Ask whether the tone is really what’s stopping you, or whether it’s the excuse that spares you from checking whether, annoying delivery aside, they happen to be correct.
