Resistant means that something can't affect it (the resistant object), or has a hard time affecting it. For example, water resistant shoes aren't easily affected by water; water cant pass through them as easily as non-water resistant shoes.
Yielding means that something is flexible or is influenced by another thing easily. For example, when you "yield" when driving, you are letting the other cars go before you; or, when an object "yields" to pressure, it is bending under pressure (though not quite breaking).
In summary: resistant means nothing can touch it, while yielding means that things easily affect it; thus, antonyms.
Words like <em>never, always, everybody, </em>etc. are absolute nouns and adverbs. In argument, these are usually a sign of over-generalization. These words alone cannot be considered as any kind of appeal (emotional, logical or ethical) since these appeals are done depending on how you use these words, not on the meaning of words as stand-alone.
