It's important to me that I validate my own transactions.
Dummy, you don't validate shit.
Any full node do validate. Any invalid transaction/not following the rules will not be relayed in the network. Bitcoin, therefore, is a validation stronghold.
You should learn how the network works, before trolling. You're an ineffective troll.

Only mining nodes can include transactions only they can validate by future inclusion of previous blocks.
Wrong. That's not how Bitcoin works. Bitcoin is trustless, anyone can run a full node and validate everything for themselves.

proves how inconsequential you are in transactions of bitcoins.
Who's pumping? I'm merely recognizing Segwit's anniversary.
